All night charging so far so good

If you where able to boot with out doing that

You should be fine. Looks like cache went back to ext4 on its own

About that dont know
[Nexus 9 Original Android Development] Scotlac:
Thanks for the quick reply!

I did wipe cache and dalvik in TWRP. Does that clear ext4 or is there a specific protocol for that?
[Nexus 9 Original Android Development] USBhost:
Yep that most likely did it
[Nexus 9 Original Android Development] USBhost:
R11.1 is up

Fixed: slow i/o :: i/o should be a little faster then R10 now

dont ask me why this keeps happing

but i think it happens when i try to enable power saving like on ElementalX, o well

i/o is more important.

Fixed: name in kernel version

Removed: more debugging :: come on wheres all this coming from lol
[Nexus 9 Original Android Development] Steffe89:
Curious.... . Although I only see the most recent 250 commits, most commits are quite old. They actually predates the release of this device and doesn't really explain why 5.1 is delayed that much or why they haven't been released in earlier updates . Will be interesting to see what these changes do for us users.
[Nexus 9 Original Android Development] USBhost:
I can tell you one thing f2fs got updated
[Nexus 9 Original Android Development] WhammyDroid:
Woohoo!
[Nexus 9 Original Android Development] USBhost:
K9.2

K9.2

-| Re-based

-| cache works for memory now

-| swap tuning

-| LMK tuning

Notes:

this new 5.1.1 kernel is ****

temperamental with being updated

Feels so much better

SWAP/ZRAM

zram is off but you can turn it on

if you want to. but you will still have 200mb of

swap, because of cache.

if you dont want it do "swapoff /cache/swap"
[Nexus 9 Original Android Development] tyvar1:
Wow you are fast! :D
[Nexus 9 Original Android Development] enriquejones666:
Sweet, Flash playback is working again with K9.2 and Dolphin 11.4.10.

(Flash playback stopped working in K9.1, but since Flash is so past its expiration date, I wasn't going to bother you with it)

K9.2 also fixed the audio sync/stuttering issue I was having with Amazon Instant Video. Cool beans!

Sent from my Nexus 9
[Nexus 9 Original Android Development] AllanJacques:
Gotta tell you, so far , so good...

Since k9 this must be on par in terms of performance!

couldnt help to notice there is no option about zram in elementalx app, is it supposed to be like this?

Anyway, congratulations!

Seems that in some intensive tasks some hickups happen, nothing major but I don't recall it happening on my dog version (K9, got it?)
[Nexus 9 Original Android Development] USBhost:
yep

Yes that because of swap that's in cache

but I say its better than reloading
[Nexus 9 Original Android Development] AllanJacques:
[QRCODE][/QRCODE]

Bad News, hanged like never before using neonotes app...
[Nexus 9 Original Android Development] USBhost:
Man I'm thinking about giving up

with LMK and swap tuning..

Should I keep trying?
[Nexus 9 Original Android Development] Ace42:
How about using same page merging, will that help? Also I haven't had a lag with 9.2.1r1 so far.

Powered by "Yeeart!"
[Nexus 9 Original Android Development] USBhost:
Yes it would
[Nexus 9 Original Android Development] AllanJacques:
Follow your heart! It led us here, so go ahead and we will keep testing!

On another note, I would put k9 as main title and not 9.2...
[Nexus 9 Original Android Development] 12paq:
Agreed! This ^^ is one of the best comments I've seen in a while. This kernel is very active and all about experimenting. We all learn from this. And it's fun to feed our flashing habits!
[Nexus 9 Original Android Development] USBhost:
K9.2.1

-| LMK tuning

-| swap tuning

-| zram restored :: but off

-| ION mem manager restored

i dont know how i forgot zram lol

it's back now.

tell me how this one goes

a good amount of things changed
[Nexus 9 Original Android Development] AllanJacques:
Going to try it right now!

Reports should follow shortly!

BTW: Are you using anything from the new 5.1.1 factory image?
[Nexus 9 Original Android Development] Megaflop666:
9.2.1 has been problem free so far. I've just been lightly messing with my n9 but so far so good
[Nexus 9 Original Android Development] USBhost:
Yep

How so
[Nexus 9 Original Android Development] AllanJacques:
Preliminary report indicate that it is working without freezes, no noticeable lag at first sight...

Let's keep testing!
[Nexus 9 Original Android Development] wingdo:
Is there anything we can do at install to allow us to be able to flash other kernels after flashing Fire-Ice? At least with version K8 once Fire-Ice is flashed the ramdisk changes prevent me from testing out the new ElementalX kernel. Right now doing a full clean install just to try out EX 2.0.
[Nexus 9 Original Android Development] USBhost:
First I would need to make the

Ramdisk gzip

Then add androidboot.selinux=disabled to the command line

And I think that would do it
[Nexus 9 Original Android Development] wingdo:
That sounds promising !!!
[Nexus 9 Original Android Development] Megaflop666:
How so what?
[Nexus 9 Original Android Development] USBhost:
O! I get it now

Nvm lol
[Nexus 9 Original Android Development] Megaflop666:
I was gonna say...

Did you want me to find a Problem with it? Lol
[Nexus 9 Original Android Development] slebit:
9.2.1 have been really stable and quick for me on aicp. I'm really satisfied!
[Nexus 9 Original Android Development] 12paq:
Same here :thumbup:
[Nexus 9 Original Android Development] Steffe89:
Unfortunately Freezing returned. 9.2.1 :(
[Nexus 9 Original Android Development] AllanJacques:
Yeah... I can't put my finger exactly where lies the problem but this new version stutters a lot... Back to dog!
[Nexus 9 Original Android Development] USBhost:
thanks

I'm getting there....

almost got the best values
[Nexus 9 Original Android Development] USBhost:
K9.2.2

K9.2.2

-| Linux 3.10.78

-| other tuning

Notes:

Im no longer dependent with init.d

all my scripts moved to FI.d

also all my EXPERIMENTAL parts are

separated now, you can enable it by changing

set=0 to set=1 in /system/etc/FI.d/01afterboot .

so it should be as fast as dog/K9 so you can enjoy all the new stuff.
[Nexus 9 Original Android Development] Megaflop666:
[MENTION=5501864]USBhost[/MENTION] - I don't see the Fl.d folder in my /system/
[Nexus 9 Original Android Development] USBhost:
Oops sorry I meant system/etc/FI.d
[Nexus 9 Original Android Development] Steffe89:
Do you have any idea why i'm the only one experiencing this issue? Could my device be defective in any way?
[Nexus 9 Original Android Development] Ace42:
What's that line running down the middle of your screen??

Powered by "Yeeart!"
[Nexus 9 Original Android Development] Steffe89:
Well I don't know. Device just freezes on certain kernal versions. Sometimes the screen is just white and sometimes there's a distored graphic line.

Version 9.1.2.r3 was the last stable for me.
[Nexus 9 Original Android Development] Ace42:
It sembles this.

http://xdaforums.com/nexus-9/help/nexus-9wi-fia-screen-flickeron-stock-t3067672
[Nexus 9 Original Android Development] taronas:
No freezes here. But with 9.2.2 I got false battery reading. System and apps were giving 30% when the device turned off without warning. Charging now, back at 15% ...
[Nexus 9 Original Android Development] cr0wnest:
Damn these updates coming out faster than the eye can blink! 9.2.2 looks stable so far, but my deep sleep drain doesnt seem very good, no idea why.
[Nexus 9 Original Android Development] Megaflop666:
Deep sleep is working for me, but I noticed there seems to be a slight lag from the previous build. The gui doesn't seem as fluid.

Do you plan making an app that facilitates the update of your kernel? It is hard to keep your pace manually. :) great work by the way!

In the meantime, you can put a browser shortcut of the download page on a home screen and check it obsessively. :D

K9.2.3

-| bcmdhd updated

-| some defconfig fixes

Notes:

I/O

default I/O gov is now NOOP.

on 9.2.2 it was deadline, i forgot to change it

to noop when i was testing, thats why some felt slow GUI

that should be fixed now

WIFI/bcmdhd

i found where google keeps the code

for it. Man that thing updates daily..

so you guys will have the latest wifi drivers from now on :angel:

R8

-| F2FS tools updated
[Nexus 9 Original Android Development] cr0wnest:
And I just flashed 9.2.2 last night!:)

9.2.3 feels a little smoother than before. I main concern would be how the idle drain is like though. 9.2.2 was able to deep sleep but the battery was still draining fast for some reason.
[Nexus 9 Original Android Development] USBhost:
please give me an image of your battery screen

When it happens

Did you turn off DTW
[Nexus 9 Original Android Development] cr0wnest:
I'll take a screenshot of it in BBS once I've let the tablet deep sleep for a few hours.

I dont think I disabled anything except the ZRAM which I set all the way to 0MB in kernel auditor. Running AICP Sabermod.
[Nexus 9 Original Android Development] wingdo:
Double tap to wake was a battery killer for me. Nice feature but not worth the drain.
[Nexus 9 Original Android Development] albsat:
The latest version 9.2.4 stuck on DU logo. I waited a while but then came back to 9.1.
[Nexus 9 Original Android Development] cr0wnest:
Alright left my tablet idle for several hours, I never touched it at all. DTW is still enabled. Here is the screenshot on BBS. Auto sync on, Wifi constantly on, location services set to battery saving. It seems better now compared to 9.2.2.
[Nexus 9 Original Android Development] AllanJacques:
Well I guess 9.2.3 is named as 9.2.4, is that it?

Anyway, this time it is much like my favorite dog (k9) and it is smooth and responsive without any hangs.

I guess your decision to separate your experimental features was a very clever way of bringing base up to speed and still keep testing!

I will keep being your test subject!

And thanks a lot!
[Nexus 9 Original Android Development] Maruli:
I get a bootloop with K9.2.4 on stock 5.0.2 (LTE) :rolleyes: , K9.2.3 works fine and smooth though...
[Nexus 9 Original Android Development] 12paq:
K9.2.4 boots and runs great here. Not encrypted, on AICP.
[Nexus 9 Original Android Development] taronas:
same here, also LTE, AOSP 5.1 ROM
[Nexus 9 Original Android Development] USBhost:
K9.2.4

I rebased my ramdisk with AICP

but it turns out lol stock does not like it
[Nexus 9 Original Android Development] wingdo:
Does this mean 9.2.4's ramdisk should be compatible with other kernels?
[Nexus 9 Original Android Development] USBhost:
I just need to fix it up a bit and it should be fine

You sir, ROCK! :good:

I will work on a proper changelog if everything is good.

OK guys plase test this one more than normal

Because I updated to the latest android-3.10.y

branches. Things changed...

So flash this one only if you want to test
[Nexus 9 Original Android Development] dictionary:
So far so good on latest AICP. Will keep running through its paces.
[Nexus 9 Original Android Development] AllanJacques:

Was that with r2?
[Nexus 9 Original Android Development] dictionary:
Whichever one you posted last night that I commented on
[Nexus 9 Original Android Development] USBhost:
O ok thanks

On r2 I decided not to merge android-tegra

because it had commits that got reverted with the new kernel
[Nexus 9 Original Android Development] omvir:
I've been using your kernel and so far so good. I was wondering if you could update the conservative governor to Franco's conservative governor on shamu?
[Nexus 9 Original Android Development] USBhost:

Yep that's it

I was afraid of that

Looks like we will have 9.2.4 instead.

[Nexus 9 Original Android Development] USBhost:
K9.2.4

K9.2.4

-| bcmdhd: updated

-| toolchain: updated :: using SM 6 now

-| Linux 3.10.79

-| ramdisk: fix boot for other ROMs

-| ramdisk: gzip compressed now

-| FI.d: some fixes

Notes:

I have been running with

experimental on FI.d and its running vary good.

Also if you flashed the 9.2.4 before

flash it again.

If everything is good

Its going stable.

ramdisk compression

I decided to go with gzip

because of compatibility reasons.

one may now install another kernel if it only

replaces the kernel. note i did not test it...
[Nexus 9 Original Android Development] AllanJacques:
So far, so good!
[Nexus 9 Original Android Development] wingdo:
WiFi has been wonky for me. It works fine and then stops. If I wipe dalvik and cache it works great again for a while. I tried to revert to ElementalX but other kernels reboot me back to recovery despite choosing system.
[Nexus 9 Original Android Development] USBhost:
I know CM is having WiFi problems

at least with me on stock is fine

My WiFi problems are normal
[Nexus 9 Original Android Development] wingdo:
I didn't have these issues prior to coming back to 9.2.4. I can't go back to EX 2.0 to verify the issue goes away. I'm not talking about minor WiFi issues, I mean all of a sudden I show no available WiFi signals. Still running Temasek 0507 and didn't have this with 8.11 either. Not sure what could have changed in addition to the kernel. Any ideas on how to flash a different kernel to see if the issue remains?
[Nexus 9 Original Android Development] taronas:
9.2.4 is fine, no issues so far, all APS working. Thanks!
[Nexus 9 Original Android Development] USBhost:
exactly I get that too but also with 8.11

I only got that problem when I updated the ROM...

but I wonder what causes it
[Nexus 9 Original Android Development] 12paq:
What worked for me to switch to another kernel after Fire and Ice k9.2.4:

Flash your ROM without flashing a custom kernel.

Boot up.

Then reboot to recovery and then flash EX or other kernel.

Done.
[Nexus 9 Original Android Development] wingdo:
Thanks, that worked!!! WiFi is stable again.
[Nexus 9 Original Android Development] dictionary:
For future reference: EX uses whatever ramdisk comes with the ROM. Fire&Ice uses a modified one. If you flash a ROM then EX, you'll be fine. You can flash F&I after no problem. However, if you flashed F&I first, EX can't use the modified ramdisk that F&I includes, so it won't work.
[Nexus 9 Original Android Development] wingdo:
I mentioned my issue because [MENTION=5501864]USBhost[/MENTION] thought he may have solved things so you could swap between kernels. Thanks though for the help as since I use Temasek reflashing is simple and painless. It's just a step I hope we eventually don't need to take. I'm just at a loss as to why I am having WiFi issues with FI that I don't with EX as otherwise F-I is my favorite kernel as I get better performance and better battery life. :good:
[Nexus 9 Original Android Development] dictionary:
Oh, okay I see. Yeah your WiFi issue is a strange one. I'm not experiencing that.
[Nexus 9 Original Android Development] dictionary:
Previously the 5/19 DU. Now the 5/20 AICP. Didn't have the issue with either, at least not at random. What'll happen for me, is on a reboot, WiFi won't connect usually. I try to go into WiFi settings and it'll freeze, and crash settings. What I've done is go back, enable airplane mode, and wait for the WiFi icon to disappear. When it does, disable WiFi. That usually gets my connection back. It's a random thing, but only occurs on a reboot for me. And not every time.
[Nexus 9 Original Android Development] wingdo:
I'm on Temasek 05/07. Other than WiFi on 9.2.4 it's a near flawless ROM. 8.11 does not experience the oddities with WiFi. I know CM has some WiFi issues, but I've never had to resort to several reboots to recovery / wipe caches daily to get WiFi to show up. It literally loses the ability to see any networks in my area. Hard reboot does nothing to help, cache clearing / ART rebuilding resolves the issue for a few hours. I'd love to help you troubleshoot, but I don't have the time at work or university to pull the logcat. Sorry I'm not a help there, but I do know I don't have the issue with stock, EX or K8.11.
[Nexus 9 Original Android Development] 12paq:
Curious. I've had these exact WiFi issues often while I was on AICP SaberMod and using F&I versions prior to K9.2.4. However, when I switched at the same time, to non SaberMod AICP and to K9.2.4, all WiFi issues stopped. Running the latest AICP and F&I, I now have no issues at all. In fact everything runs great. I've assumed the WiFi issues were from the ROM, but I have no logs or data to support that. Hope this helps.
[Nexus 9 Original Android Development] USBhost:
I second this

just updated to 5.20

no WiFi problems
[Nexus 9 Original Android Development] dictionary:
I'm counting it as a non issue for me. It only happens on a reboot, and I don't really do that often unless my crack flashing kicks in. I'll start a log next time I reboot if it'll help, but I think my issue is different from his. Not extreme at all.
[Nexus 9 Original Android Development] AllanJacques:
Well, I guess we achieved top performance...

(and by we I mean FIRE-ICE)
[Nexus 9 Original Android Development] USBhost:
Yep

I'm moving on to memory management

cache is my test subject haha!!
[Nexus 9 Original Android Development] 12paq:
Just had no WiFi after boot up. I grabbed a log, but it might not have caught the issue.

http://pastebin.com/LzHdtY6d

I am unencrypted, on AICP nonSaborMod 5-20, and F&I K9.2.4

If need be I can try to replicate the problem and pull the best log, but might need a little direction on what log commands are best. I'd like to know for sure if it this is a CM based rom problem or not.

Everything else is running good.

Thanks!
[Nexus 9 Original Android Development] USBhost:
can you try 9.2.5.r2

I did 3 reboots and WiFi still good
[Nexus 9 Original Android Development] dictionary:
I've already changed ROMs, but on the latest SLIM, r2 boots with signal. Forgot to check the old 9.2.5.

May be just me, but does r2 default to ElementalX instead of Interactive?
[Nexus 9 Original Android Development] USBhost:
Nop Interactive
[Nexus 9 Original Android Development] dictionary:
Maybe my wife changed it on me without my knowledge. Okay, sorry lol
[Nexus 9 Original Android Development] 12paq:
Tested 9.2.5.r2 a few times, so far no problems with WiFi on boot. :thumbup:
[Nexus 9 Original Android Development] preacher65:
Just had my first experience of no wifi on boot. Today I did a full wipe from Temasek to AICP latest, ran it for a few hours, then flashed 9.2.5.r2 and on first boot there's no wifi. I can turn wifi off and on again but can't see any SSIDs. Before I try a reboot to see if that fixes it, is there any kind of logging that would be helpful in case you wanted to take a look? A logcat or something else?

Edit: Had Settings FC trying to toggle wifi while grabbing a logcat. I'd reinstalled a lot of apps by the time I flashed the kernel, so I'm not sure if any of this is caused by apps, ROM or kernel, but I can't get into wireless settings, so going to have to reboot eventually. Have attached the logcat that I managed to take (had to zip it, sorry) but don't know if it will help. I'll restore a nandroid later but will leave it as it is for now just in case there's anything I can do that would help, if any of this turns out to be related to the kernel.
[Nexus 9 Original Android Development] USBhost:
can you give me a kernel log

dmesg
[Nexus 9 Original Android Development] Megaflop666:
Latest build has been great so far. I have not experienced the WiFi issue yet.
[Nexus 9 Original Android Development] preacher65:
Thanks, file attached.

Edit: Went to check the device and wifi was turned off - not surprising as I'd been trying to toggle it but it wasn't responding, so I'm not sure which command I last gave it. However it now responds and when I turned wifi back on, I could see SSIDs and connect. Just posting in case it's helpful, not really sure this is a kernel problem...

Edit: Don't mean to pester about this, but in case it's helpful, I rebooted this morning and same issue. New dmesg2.txt file attached. I can try a clean wipe and flash kernel before restoring apps but leaving things as they are for now just in case it's of any help.
