Maybe.

At least once per day, usually when loading a game (which I am deliberately doing to test Zram etc) I will get a frozen phone. It's different than any freeze I have ever experienced. It usually stutters, freezes...and if I am lucky enough to get it to go into standby (at snails pace) then when I turn the screen back on, I get an option to f/c the app/game. If I f/c, my system is usable again without rebooting.

It's as if everything is running in harmony, but at the launch of said app/game, the system freaks out because it can't provide something??? It feels like an OS that is starved of RAM. I just had it happen with a neat free app I was testing called Androsensor. (gives great sensor and stats)

My advice,

update to 3.7.6 and get it all booted up and happy. Then install Dx Kernel 3.7. You will likely have a smoother go of it this way.

As another User mentioned....VOLUME+ from market may work, or manually edit etc/init.d/14mic_level. Each of the 5 category levels can go from 1-1000.
[HD2 Android NAND Development] Realalist:
Use Root Explorer system/etc/initd and adjust the mic 14
[HD2 Android NAND Development] themadproducer:
System crawl, screen freeze etc.

hey Dorimanx,

3.7 is running fine except for the already mentioned occasional screen freezes which I seem to be able to crawl out of without rebooting but they are severe. It resembles the feeling of LOW RAM or super low CPU.

It just happened again after I installed a new version of Current Widget. I went into CW settings...nothing fancy or weird...but the system went into a crawl....like it's 99.9% frozen. There seems to be no specific app triggering the issue.
[HD2 Android NAND Development] jookdakang23:
when i make a call with the new dorimanx kernel i have no sound then when i hang up the phone slows down to being unusable. when i go back to 3.6 everything is fine, what could be the problem
[HD2 Android NAND Development] themadproducer:
Are you installing the NO-CALL REC version? This is the one to use to avoid similar issues.
[HD2 Android NAND Development] jookdakang23:
yes i am and it only occurs on 3.7 for some reason

---------- Post added at 07:52 PM ---------- Previous post was at 07:45 PM ----------

i guess ill just stay on 3.6 til 3.8 comes out :(
[HD2 Android NAND Development] Looki75:
Hello Dorimanx, I experience exactly the same issue each time I install a new app...

I hope you can fix it, because otherwise, this new version is fantastic!

Thanks
[HD2 Android NAND Development] jolas:
Yes, happened to me too, today.

I'm using MIUI ROM, ext3, ZRAM and 256MB swap partition...

---------- Post added at 12:27 PM ---------- Previous post was at 12:23 PM ----------

+1

Do you use swap partition? (I'm thinking that maybe it is because the swap partition is getting full... :confused:)
[HD2 Android NAND Development] themadproducer:
No Swap partition, but yes to 18% Zram. I am now testing 3.7 without Zram to see if things work better. I will report back after a day or if the issue remains...which ever comes first.
[HD2 Android NAND Development] dorimanx:

@Dorimanx,

Can you make as an option in 3.8 for other ROMs (MIUI or Sense) to choose between BFS or CFS scheduler?
[HD2 Android NAND Development] corrsea:
Occasional BSOD plus market download issues with 3.7 on ics CM9.

Works perfectly for me though on CM7 gingerbread.
[HD2 Android NAND Development] themadproducer:
Great to hear Dorimanx.

Thanks for the communication updates.

I am going on 12h+ with 3.7 and Zram disabled. No sign of slow downs.

Real Ram is behaving and seemingly games sometimes start 20-40% faster than they do when using Zram. (as always) But I will be anxious to test out 3.8 when your ready. And, I will re-enable Zram at that point.
[HD2 Android NAND Development] jsbath:
I have a little problem and see if you can help me.

with kernel I stick the file initd and recompress it zipped recovery well when I open it but abort the upgrade. I'm doing wrong or should I do?

sorry for my english

thanks
[HD2 Android NAND Development] themadproducer:
Open kernel zip package with newest version of 7zip. Dont uncompress it. Just open it...and drag and drop what you want inside it....etc. assuming thats what your asking. otherwise, just put it on your sd card and install from CWM. Dont choose UPDATE in CWM, JUST CHOOSE install zip....etc.
[HD2 Android NAND Development] Fietspomp:
Downloading 3.8, I use ICS Rom from Michie.

What are the best settings?

I guess:

NO-2WAY

NO Busybox

NO Zram

NO VPNfix.

Am I right? Or will Zram work under ICS?

Thanks for all your hard work and dedication!
[HD2 Android NAND Development] dorimanx:
NEW KERNEL 3.8 in my mirrors!!!

Look at front page :)

[HD2 Android NAND Development] dorimanx:
zram will work, but you need to install standalone activation script! get it from front page.

ICS dont have settings for compcache (zram) so only manual (on boot auto activation from init.d)
[HD2 Android NAND Development] Fietspomp:
Cool thanks for the advice.

BTW, I've noticed a small bug (I think).

At step 2, you can choose from CM7 of MIUI/ICS.

When I choose ICS, the phone would not boot. (Also step 4 was ICS).

But when I choose CM7 at step 2 and ICS at step 4, it boots fine!

Or did you mean for step 2 a MIUI ICS rom?
[HD2 Android NAND Development] dorimanx:
ooo yes its a bug, the init.d from sense is loaded. and no boot. i need to fix it.

if someone have initrd.gz for ics, i need it to complite the ics menu.

[HD2 Android NAND Development] Rick_1995:
You can shift to github without losing your commits from gitorious.

Go to the folder where you have the kernel code for gitorious set up, then execute following

Create a new repo on github with "projectname"

git add remote github git@github:yourgithubusername/projectname.git

git push github --all

(Also you have to setup for github before, like ssh keys and other things but since you already have a repo there, i believe that is already setup).

My Rom Uses tytungs r1 kenel. I am testing Dormiax 3.8 kenel and so far no freeze. where did your phone freeze.
[HD2 Android NAND Development] themadproducer:
96mhz

Dorimanx,

At first I did not notice the 96mhz frequency.

I was able to select it via SetCpu

Looking at the current VDD levels, I see that 96mhz is at 950-975mv...which I assume is the default value since there are no preset in 15cpu_voltage that pertains to 96mhz. Is that on purpose or just something you haven't tried yet?

Perhaps I will test 900-925mv.

So far, 3.8 running smooth as can be with Zram disabled for now.

I still notice that within 24hrs, available free ram eventually diminishes to well under 100mb from original 195 (that's with apps preloaded into memory)

I will be testing Zram in the next few days. I think the issues I was having with 3.7 were Zram related.

---------- Post added at 03:04 PM ---------- Previous post was at 02:50 PM ----------

Good question.

At the moment, it is my security blanket. :D

It's a daily driver that is very stable because there is not much experimenting once core features are working.

But when I first jumped from SD builds to Nand, there were some issues with Hyperdroid beyond the core ROM...not to mention the theme and dpi was non standard or not to my liking. The Dorimanx rom did not exist yet. Some people, especially less experienced, don't realize that the core ROM is something that Typhoon, Dx and Hyperdroid all share. The Typhoon rom is simply the closest to STOCK....the least amount of mods needed to make it run whereas Dx is cutting edge, mega feature rich additions...but a bit experimental....just like this Kernel. I mean, I could have stuck with Tytung r14 Kernel....it works fine, but I decided to follow Dx's kernel not only because he is a monster modder/Dev....but switching Kernels in and out is quick and painless compared to switching roms. I have the same Typhoon rom from 10+months ago. Only one single clean install...that's it.
[HD2 Android NAND Development] Axel85:
ok now it s working...all i can say with zram enabled is:

This phone is great and your kernel is AWESOME ,the phone now is about 30% faster,smother,even hd games like real racing 2 now run about 30% faster and even without using any chainfire .I have this configuration :

thyphoon rom, your last kernel,cpu @1612,and my phone run almost the same as galaxy s2 (tested performance in os and games,not in benchmark)

Guys, I had some reboots out of nowhere

Anyone knows what might be cause.

Not even using any hi drain apps.

On Typhoon rom, dorimax latest kernel, clk, T-Mobile hd2.

Using go launcher, go SMS, Rocket Dialer. No games.

Thanks in advance for any help or ideas.
[HD2 Android NAND Development] themadproducer:
PROCEED WITH CAUTION.

Simple Way.

Use Root Explorer, go to etc/init.d/15cpu_voltage. (click mount r/w) then long press 15cpu_voltage and choose "open with editor". The top area shows freqs and the corresponding STATIC millivolt setting. The bottom area shows the DYNAMIC versions which have a low and a high value. So for the case of 96000mhz I used 900mv for the STATIC area and 900-925 for the dynamic. (depending on the rom, the static or the dynamic values will be used)

To make it work, you need to reboot. OR alternatively, use something like Gscript light...and create a script with SU that has this... etc/init.d/15cpu_voltage. Name it whatever you like. Running this will take the values of 15cpu_voltage and apply them without rebooting. If you mess up and your phone freezes and wont reboot, you can reinstall the file or simply the entire Kernel package.

To verify that your new settings are applied, check cat/sys/devices/system/cpu/cpu0/spufreq/vdd_levels_havs.

Finally, for me...to make the next Kernel update easier, I edit 15cpu_voltage right on my PC with Notepad++ and I place it inside the NEXT NEW kernel package before installing it. For Typhoon rom, it goes into1-cm7-system/etc/init.d overwriting the stock version.

PS Ignore the 19200 values. It's not used with our HD2s. I believe it is a deep sleep state value that we can't use???
[HD2 Android NAND Development] general1977:
Sure the HD2 goes into deep sleep. At least CPU spy says so. But we can't change any settings for it, I believe.
