any of u guys experience this? starting with nightly 64 until now, when i use this kernel or even the HD version 5, i cannot restore my apps using titanium backup or even install from market or install any apk. The device will simply just reboot. so i would re-flash and use the stock CM7 kernel and i don't have that problem. too bad, when i was using 57 and 4.5.2, i never had this issue. btw, im also using the -50 script.

If you guys have any idea why this happens, kindly help me. I really want to use this kernel.

Thanks a lot.
[Desire HD Android Development] inzaghi75:
I think you must take for Build 57 a lower Version Kernel like 4.4.1 or you flash the latest Build #66 with the 5.0 or 3.5 HD Kernel.

"Use 5.0 CFS or 4.5.2 BFS V400! - ONLY later kangs than nightly 57!!! for n57 or older use lower kernel version. 5.0 is based on nightly 64"

cm7 nighty 65

first time user i downloaded and flashed 5.0cfs on cm7 65 nighty , what is the call recorder apk thats asking for super users permissions ? also what is the best kernel here for speed and stable ? and are all different kernels here based on 64 nightly or just the 5.0 ?
[Desire HD Android Development] BumAround:
Read the first post and follow this thread closely (like at least 5 pages backward).:)

Call Recorder is to record EVERY call (incoming/outgoing) and save it. So make sure you clean up the recorded files often before it fills up your SD card, or you can just disable it altogether.

I'm using nightly #64 and v3.5 (LordMod's other kernel HERE) and doing just fine.
[Desire HD Android Development] espressofrap:
As I've mentioned in my post, I had no problem with 57. My problem is using v5 or v3.5HD kernels with the latest nightly. Thanks.

[Desire HD Android Development] BumAround:
Thanks for reporting it, espressofrap, I was about to use LordMod's v.5.0 with nightly #65.

btw, did you wipe everything/factory reset?
[Desire HD Android Development] espressofrap:
yes, that's kinda standard for me. always full wipe of everything... I don't know if i'm missing anything. i would assume that IF its really a known problem then a lot of people would have already reported it. so maybe its just me doing something wrong. but i can't figure it out. tried different combinations using nightly 64, 65, stable 7.0.3 and 66 with both version HD3.5 and version 5 of Lord's kernel but its the same problem. always reboots when i install anything, be it from TB, from market, or just an apk file. I believe it has something to do with the kernel since i don't have this problem when using the stock CM7 kernel that comes with the ROM.

I would really appreciate anybody's help on this one.. thanks a lot in advance..
[Desire HD Android Development] inzaghi75:
But I`m using Build #66 with HD 3.5 Vio Kernel and PUV-25mV Script and i have no problem. Do you installed the latest Gapps? Do you flashed one of the script from LordMod? Which Radio do you use?
[Desire HD Android Development] michelD:
Hello,

I have absolutely NO problem with NB#65+LM kernel V3.5HD or V5.

+ radio26.09.04.11 +ril2.2.0131HM.

Power consumption is also very acceptable: only -4%/8h screen off without undervoltage.

BTW, I am a little bit cautious about undervolting: generally I can aplly -50mV, but in this case I have, from time to time (say once a day), strange behaviour like unexpected crash, autoreboot. And even with -25mV I still have (but even more rarely) unexpected behaviour.

So, personnally, I prefer a rock stability than to spare some few percent of consumption.

Indeed, FYI, the power consumption is following this formula:

P= k * F * V²

P= power consumption [W]

k= a constant depending on the technology

F= frequency

V= core voltage.

The core voltage being around 1 Volt, a reduction of 50mV will reduce power consumption of ~10%.

I don't want to say that it is nothing, but personally, I do prefer stability.

Have a nice day

I flashed v5 on CM7.0.3 but I'm having WiFi issues. It can't connect, just keeps trying and trying.
[Desire HD Android Development] BumAround:
inzaghi75 which radio are you using?

lately I've been experiencing high batt drains out of nowhere.

no new apps, only k9 push email updating every 48 mins (but previously this didn't result in higher drains).

I've tried build #64 and #65 (nightlies), always full wipe, tried both v3.5 and v5.0 with PUV or UUV.

this batt drains really annoys me, i.e. ~5-7% per hour from previously ~1.3-2.5% per hour (with push email and trillian for messengers). :confused::confused:
[Desire HD Android Development] inzaghi75:
I`m using the latest Radio 12.54 and the RIL of this Radio. Battery Drain is Ok. I must look how much battery drain I have in a hour.

Do you have 5-7% on Standby?
[Desire HD Android Development] BumAround:
Unfortunately, yes. (with one push email on k9 and trillian which is a messenger client).
[Desire HD Android Development] michelD:
Personnally, I have ~ -0.5% /hour in stanby (with 2G/3G + wifi off and 122Hz max cpu freq in standby).
[Desire HD Android Development] BumAround:
I used to have ~ -0.5% to 0.99% per hour on standby (with one push email auto syncg-ing on k9 client, OR with one push email auto sync-ing on k9 client plus trillian client for YM).

I believe latest nightlies are the usual suspects rather than the kernel(s).
[Desire HD Android Development] LorD ClockaN:
New version UP..

Hopefully fixed the confusion between nightlies, stable, miui.... etc
[Desire HD Android Development] justaguy84:
wlan doesn't work for me on 5.1
[Desire HD Android Development] LorD ClockaN:
which version BFQ or VIO?

which ROM?
[Desire HD Android Development] justaguy84:
5.1 and LorDModHD 3.6 bfq running cm 7.0.3

I think that it's maybe rom problem.

4.5.2 worked but only after 10-15 minutes.

5.0 didn't work at all

5.1 and 3.6 wlan is working (you can see stations) and it tries to connect, but it doesn't work
[Desire HD Android Development] michelD:
Cyan NB#69 + LordMod kernel v5.1VIO working perfectly for me: WLAN, gps, etc ok

Thanks !!
[Desire HD Android Development] lampz:
Cn anyone upload via dropbox please the 5.1 bfsq??

Clockan please.. thank you! Cnt dl via webbrwser

whats the difference between LD HD3.XX and LDV5.XX?

please give some short definition..

anyone? or care to explain..
[Desire HD Android Development] michelD:
It very simple: if you had red the first page, you would know that:

- LordMod HD 3.XX kernels are based on Linux kernel 2.6.35.13 while

- LordMod V5.XX kernels are based on Linux kernel 2.6.32.39.

As simple as that, but may be you don't have time to read....

PS: if you want to know the differences between Linux kernels 2.6.32.39 and 2.6.35.13, pls google !!
[Desire HD Android Development] lampz:
Lol i knw abt that -.- dnt you thnk i dont? Haha

My fault tho. I wasnt able to complte my question..

Whats the diff of the 2 kernel base on your experience. Which ones better for you?
[Desire HD Android Development] djamorpheus:
I can confirm this too all is awesome!
[Desire HD Android Development] apsis:
Well i use lordmod 5.0 cfs vio now on cyanogen stable 7.0.3 and wifi and also my camera are working now again. So maybe the wifi issue is the reason from the constellation of radio,ril and kernel.

I'm using the latest gingerbread radio and the ril that belongs to it. Wifi /media /camera is working. Thx for your work mate
[Desire HD Android Development] justin0307:
Flashed 5.1 VIO CFS on nightly 70, wifi/video/camera are all working :)

There's a little bug. It shows 5.0 in settings :D

I'm trying kernel 1.2.2 on CM7#35. "Plain" is working fine, SD_patch just dies after a few seconds.

And there is something wrong somewhere. With CPU a 1.6GHz I'm only getting 1300 in Quadrant standard whereas I get ~2400 with default kernel.

Cheers.

EDIT 1: trying to set smartass governor in SetCPU causes immediate lock of device.

[Desire HD Android Development] d.brown:
same here with the sd patch and the plain... but mine was in interactive
[Desire HD Android Development] sonydesouza:
Hi,

At first, thanks for your hard work...

Sadly, i tried new kernel with sd fix and my phone freezed at startup (wipe done before of course...)

I restored my backup..So, no problem...

Anyway, i will try later ;)

I'm on RC4 CM

EDIT : after a second try, everything is erased in my clockworkmod...Too bad...
[Desire HD Android Development] Giloux1:
I'm on CM7 RC4.

One freeze with kernel v1.2.2 at 1804 Mhz. After reboot, no more freeze.

Stability? Don't know...

Why go to 1958 Mhz? Why not limit to 1804 Mhz for more stability?

Anyway, nice work in progress... And thank you!;)
[Desire HD Android Development] angelus249:
cm7 nightly #35, your kernel 1.2.2

min 122, max 1209, smartass

screen was off; after pushing power button screen came back, lockscreen was shown and then "freeze". couldnt even unlock the device. guess it's the 122mhz. will try it another 1-2 days. never had a freeze before after turning the device back on.

edit1: ok. after lying around another 2-3 minutes, it froze again, when i tried to unlock it again. will try next step. 268 or whatever it is.

edit2: 245mhz causing no problem at all. too bad, every now and then some ppl tried to do the 122 mhz during the past months.. but obviously not successfully working for everbody - at least for now.

edit3: now again some weird behaviour... after turning the device back on it was not only a freeze, but a reboot as well shortly after it froze ... but the device worked some seconds before, not instantly like the freezes before. you got some severe issues with this version. going back to 1.1
[Desire HD Android Development] angelus249:
and with "dies" you mean...? The value in /sys/devices/virtual/bdi/179:0/read_ahead_kb is back to 128? Or you just don't feel the improvement?

It won't have any effect on quadrant benchmarks!

i also compared the script with my own one, which i slightly modified from http://xdaforums.com/showthread.php?t=1010807 and can't see, why the sdcard patch shouldn't work. or at least why applying the patch shouldn't work.

@lord: the only difference i see, you grant more rights to the init.d directory, 755 instead of 750 in the original fix posted above. but i can't imagine, why too much rights would affect the proper working :)

btw. i get "best performance" with 3072. not the default 2048 used here.

despite all that i doubt the real improvement of the sd fix :) which apps or pictures or music wouldn't load quick enough while card is mounted?! when card is mounted via usb e.g. on a windows machine, the sdpatch wont have any effect at all.

greetz
[Desire HD Android Development] Drew442:
Performance is no where near v1.1

These are both at 1958mhz and performance governor.
[Desire HD Android Development] LorD ClockaN:
It's funny how for some folks kernel works, for some isn't..

The hardest thing is that I get zero crashes and quadrant scores are high as 1.1

1.1 was slugish for me, bit for you guys it's OK.. sd card read fix makes wonders for me when browsing gallerie and pics..

For the next bersion I'll try another approach to cpu freq table, remove the sdcard read patch. Bit will leave 122mhz but sligtly higher voltage...
[Desire HD Android Development] lampz:
the latest from cm7 is 2.6.32.35

and this is .38 right? the new one from kernel.org?

patchd to 38?

And much data on my SD became junk. Some files just diappeared and some other have zero length. This kernel be damned.
[Desire HD Android Development] s_yarrow:

[Desire HD Android Development] bratboo:
Hi!,

Everything is working fine for me with v1.2.2 using nightly36. I'm getting better battery drain than the stock kernel from RC4. On sleep mode I only get 1mah to 7mah mostly are on 3mah. Also my music drains are on 50-60 while on stock on 70-90. Smartass are now stable no more lag even on 1ghz.

Hope to see more updates!

Anyone know of a way to fix this?
[Desire HD Android Development] chardd23:
oh hai guise.im currently using the kernel that is included with the CM7 RC4.

What can i expect if i flash this kernel over my ROM?

and what is SmartASS governor?

how does it differ from other governors?
[Desire HD Android Development] LorD ClockaN:
****.

how can I develop a kernel when half of you here give positive feedback, and half negative..

That is too weird..

Will try to revork cpu table again with higher voltages to be more stable
[Desire HD Android Development] stony2k:
HD 3.6 kernel is working fine with CM for me. Try this at first.

kernel patched to .40

and few tweaks to governors
[Desire HD Android Development] BumAround:
2-way recording gone, I presume?
[Desire HD Android Development] LorD ClockaN:
no.. why do you presume that??
[Desire HD Android Development] BumAround:
Because on post #1 there's a line inside the gray box (kernel's description) stating "Implemented 2 way recording patch by avs333 and skvalex - thread - only kernel 4.4.1 and now 5.1" :)

...Still fighting high batt drains (not related to the kernel, but can't figure it out as yet) :confused:
[Desire HD Android Development] LorD ClockaN:

What are the differences with LordModHD kernel ??
[Desire HD Android Development] inneyeseakay:
Which version to use with CM7.0.3?
[Desire HD Android Development] Setsuna666:
Afaik the kernel base are different. This one use 2.6.32.x while the other one use 2.6.35.x.

Using a newer kernel might provide better performance and other enhancement. If you are the kind of person who like to use the latest software release, go for the newer kernel, otherwise keep this one.
[Desire HD Android Development] stony2k:
They'll all work with MJDs (Cynogen Mod based) roms :)

Different kernel base.
[Desire HD Android Development] LorD ClockaN:
yes

@inneyeseakay:

[Desire HD Android Development] michelD:
Hi My Lord,

1° Cymod #71 working perfectly with Your Kernel LMV5.5 VrI/O + Radio 26.09.04.11M2+RIL 2.2.1003G. Battery drain is also low (-0,5%/Hour in standby)

2° I notice that with Cymod based on 2.3.4, the SD read performance is lower (~8.2MB/s) even with a read ahead buffer of 2048KB = default value with last Cy releases (/sys/devices/virtual/bdi/179:0/read_ahead_kb). Could it be related with the kernel? (NB: same situation with your 2.6.35.13 kernels). With Cy 2.3.3 the peak read speed = ~25 MB/s).

3° In V(R) I/O what value are you using for R ?

Thanks for Your kind attention
[Desire HD Android Development] LorD ClockaN:
I don't think that kernel is the issue..

if you are using flashed zip for script from first post.. it's not working for 2.3.4

you must copy it manualy to /etc/init.d folder, give it executable permissions and reboot!
[Desire HD Android Development] michelD:
Yes, it's what I did, but I don't have to use it with last Cy NB releases, because 2048 is now the default value of the read ahead buffer ( see /sys/devices/virtual/bdi/179:0/read_ahead_kb).

Thanks for your answer.

EDIT: sorry, I'm not sure that it is now the default value, because I just remerber that I made a script to set automatically 2048 at boot. But anyway, the SD read performances seems much lower with the Cy NB 2.3.4 family.
[Desire HD Android Development] marshy73:
I'm not sure if this is a Kernel issue but perhaps if someone mght know the cause... appreciate the advise.

For youtube videos posted on forums, i can playback the video but screen is black. Audio is ok.

All other methods of youtube playback is fine.

Problem only in embedded youtube videos on forums or webpages.

Hi all,

I am on MIUI and flashed Lordmods latest CFS kernel with the uuv and puv, but when i install apps my phone reboots? i have no idea why ): please help
[Desire HD Android Development] michelD:
Probably because you undervolt too much your phone that do not support uuv nor puv. So use the restor default script or zip in page 1, and probably everything will go smooth.
[Desire HD Android Development] substance12:
4.6 was only for kangs. now that we're at 5.5, does that have the same restrictions or is that for everyone? i'm currently on 4.5.2 cfs bfqhs
[Desire HD Android Development] LorD ClockaN:
zero restrictions
[Desire HD Android Development] marshy73:
Can the undervoltibg scripts be used in other kernels? Eg cm original kernel?
[Desire HD Android Development] jpinky:
nope, only in kernels which use the same sysfs VDD interface. AFAIK CM7 does not have that implemented by default at this stage.

Leedroid for ex. can (3.03)
[Desire HD Android Development] marshy73:
Thanks.

So lets say i am already running on one of the undervolt scripts and I wanna change to a different kernel that does not support this script. Can i just change kernels just like that? Or i should run the default voltage script first?
[Desire HD Android Development] ErOR22:
You can just flash new kernel, no need to reset voltages.
[Desire HD Android Development] Drew442:
2.6.52.40?
[Desire HD Android Development] Drew442:
Leedroid isn't using ACPU so the table is different.

You use the same syntax for the VDD sysfs interface but the frequencies are different. Modify the script in /system/etc/init.d with the correct frequencies.

The patches will go straight on MDJ's kernel's though.
[Desire HD Android Development] stony2k:
Just to be sure I would recommend to use the Restore defaults zip from frist page. Only just to get sure (if you change on a complete different kernel)
[Desire HD Android Development] marshy73:
One issue i've never encountered before till I flashed 5.5 VIO. Randomly, my ringer and notification volume automatically gets muted i.e volume 0.

I setup volume back up again and later it'll get muted again with no intervention on my part.

[Desire HD Android Development] justin0307:
Did you accidentally used the profile setting in cm7? I don't recall anyone in this thread had reported this issue before.
[Desire HD Android Development] marshy73:
Nope. I've never ever touched profile settings on the phone.
[Desire HD Android Development] justin0307:
Not sure what the problem is, but have you tried to reflash cm7 or the kernel?
[Desire HD Android Development] marshy73:
I changed to 5.1 and now just changed back to 5.5. Observing if occur again. Cache and Dalvic Cache always wiped
[Desire HD Android Development] justin0307:
Hope it's gone :) weird things happen haha.

If it's still there, try reflash cm7 and see :)
[Desire HD Android Development] marshy73:
really frustrating.

I reloaded cm703 then followed by 5.5 VIO.

Problem still there... randomly the ring and notification volume gets muted.
[Desire HD Android Development] BumAround:
Happened to me too but on 7.0.2, forgot with which LordMod's kernel though (v.4.6 or v.5.0), it's intermittent.

Then it's gone with CM7 nightly 71 onward, stick with LordMod's v5.5.

Wipe everything clean (cache, dalvik, factory reset, format /system, reset the script, in this order), then install the nightly, followed by the radio ril by mounting the system first, reboot, and then the undervolting script, reboot again, and the kernel. Restoring nandroid is the last step. No prob ever since.

Not sure what is the culprit. :confused:
[Desire HD Android Development] jags_the1:

Should I flash the voltage zips after i flash the kernel or before i flash the kernel? Can I flash all these voltage files one after the other or I should flash a zip > reboot phone > reboot recovery > flash next zip and so on?

How would I know if my DHD is compatible with UUV or PUV? If it ain't compatible, is there a serious threat to my device?

thanks in advance for your help.
[Desire HD Android Development] michelD:
Flash the niew kernel and test it. If ok then apply undervoltage script step by step from -25mV to the max possible without having strange behaviour.

Have a nice sleep...
[Desire HD Android Development] tahiriqbal:
step by step, you mean, i should flash the -25mV in recovery then reboot phone and test it if everything is ok, then i should go ahead with next file and continue the same process?

Thanks in advance!
[Desire HD Android Development] justin0307:
Ya that's right. When it doesn't reboot or freeze during use, you can move on to the next script. Once you found out how much your phone can handle, next time you flash a new kernel, you only need to flash that script. You don't need to go from -25 to -50 to UUV and so on. :)
[Desire HD Android Development] tahiriqbal:
great... thanks for helping me out with this. I will follow the steps you mentioned.

thanks again!
[Desire HD Android Development] justin0307:

Should I delete cache and dalvik cache each time when moving from -25 to -50 to UUV etc ?
