After recover from a reboot, directly "cat /proc/last_kmsg" over Terminal Emulator and give me the output.

This kernel has nothing to do with lockscreen rotation. Open Settings - Display - Rotation.
[Galaxy Tab 2 7" Android Development] zeetherocker:
Sorry sir.. The lock screen is in landscape when its locked.. I thought the default orientation in this kernel is landscape... And I've changed the hwrotation value from 270 to 0 in build.prop.. Maybe that's causing the problem.. But thanks for your response...
[Galaxy Tab 2 7" Android Development] antutu:
Bro, currently i'm using slim bean and mokee open source.

Both hwrotation set to 0 and guess what in slim bean lock screen is orientation dependent and mokee lock screen only landscape.

It has nothing to do with kernel.

For our platform, cleancache need zcache for Transcendent Memory. Without a working zcache, cleancache is useless and slow down file systems access a bit.

Hey ketut.kumajaya, I've got question.

Is it possible to add game pad support into kernel? Other tablets (for example nexus 7) support natively xbox pad when with our gtab it has power but it isn't recognized (even with usb/bt joystick service). I've tried xbox wire pad, xbox wireless pad (with pc dongle), chinese noname pc pad: none of those work. So, maybe there is any kernel module which can make them work? By the way, excellent work.

Issue with "recent Apps" button

Don't know if this related to CM10.1.2 or Blackhawk's kernel. Some times after starting my Tab it works fine/normal, the recent apps show up and can be reopened or discarded either individually or cleared bulk style. But sometimes nothing shows up on the screen, even though there should be. No apps and no clear button. Any suggestions? By the way, I did try some different button layouts by way of the settings option. Would reflashing CM10.1.2 or reflashing the kernel be the best place to start?

Thanks:confused:
[Galaxy Tab 2 7" Android Development] Android-Andi:

Seems 1.6.3 oc version is a bit smoother than previous but only when zram is disabled. somehow i experrience many lags when zram should have been working and memory is needed.! disabled it and now everything is smoother, meanwhile i can say that there is no visual difference in battery consumption.?!?
[Galaxy Tab 2 7" Android Development] ketut.kumajaya:
Yes, cleancache with a working zcache help for smoothness but still not sure "zram for Android" really works :(

So, I've borrowed next pad but now with reciver. Here is output (errors, errors, errors) https://www.dropbox.com/s/kr5oxzyabo6237u/dmesg5.txt Strange thing that I've noticed is led on reciver - it's not turned on like with pc but device has power because when you hold sync button led is flashing and reciver can sync to pad.

OW Well It's working: something wronh was with the cable!

About zram: I feel more smoothnes since I've turned zram off. Even my stupid Sunbeam wallpaper is teling that me :D : with zram it's laggy as hell, without it's almost smooth. Btw. I was always thinking that zram, compcache is for devices with small ram like my x8 :P.

[Galaxy Tab 2 7" Android Development] ketut.kumajaya:
Did you mean yours wireless receiver detected as 0x045e vendor id and 0x028e product id? If it's correct, the key layout already on our device both on stock and CM.
[Galaxy Tab 2 7" Android Development] iks8:
Yes, I've change name to Vendor_045e_Product_028e.kl as it was previously. BTW if I want to install modules on every boot I need to add insmod commands into hw_config, right?
[Galaxy Tab 2 7" Android Development] ketut.kumajaya:
Great! Yes, I will add it in next version including LED support but with LED, xpad module will not compatible anymore to stock kernel. Yes, the already shared Xbox support modules should be compatible to stock kernel, you can start a thread in General sub forum about this solution. To load kernel modules on every boot, add:

insmod /data/local/tmp/ff-memless.ko
insmod /data/local/tmp/xpad.ko
insmod /data/local/tmp/joydev.ko

to /system/etc/init.d/02modules. This is a temporary solution for now.

[Galaxy Tab 2 7" Android Development] 5h1v4u:
I currently have Pac man rom installed and I have a backup of cm 10.1 nightly.. I restored the cm and flashed the next kernel then philz touch.. I then flashed the next tool and created a system image (2nd option) then booted to secondary recovery .. I then tried to restore the Pac man rom (which I took a backup of) but it stays on Samsung logo.. as of now I am back on my Pac Rom with next kernel.. both the roms are 4.2.2 .. have 3.5 gb of internal storage and 5 gb of external.. so I'm not sure if this process is even correct

I missed clearing cache party and flashing the next kernel after resorting the cm..

So I will now try to keep the Pac man as primary and restore cm as secondary.. I'll let you know the results shortly

[Galaxy Tab 2 7" Android Development] dimfil:
What do you mean?

If you want to know how to revert to another rom and kernel, you can do it just by flashing them through recovery.
[Galaxy Tab 2 7" Android Development] Skazzy3:
If you want less heat then use it.
[Galaxy Tab 2 7" Android Development] chazy chaz:
i already tried that before asking him this question, guess what ... didn't work !
[Galaxy Tab 2 7" Android Development] dimfil:
That's impossible...

I have already done it a lot of times...

The procedure is the same for every custom rom change:

- boot in recovery

- format system partition

- wipe data and cache

- wipe dalvik cache

- install rom zip

- install kernel zip

- reboot

That's the way it works...

Well, there is no obvious reason for this happening to you. I have "jumped" berween roms and kernels several times in the past few days, including of course ketut's NEXT kernel, trying to test several combinations of dual booting and each and every time starting from clean single boot.

I installed from scratch ad well as from backups.

Never faced a problem like yours...

I see that there is no other report with such a problem...
[Galaxy Tab 2 7" Android Development] ketut.kumajaya:
Do not have plans to build a kernel without overclocking capabilities. If heat occurs in CM based ROM with 800MHz CPU frequency setting and default GPU clock, then the problem is almost certainly not the kernel but your device.

From gokhanmoral's thread and applied here as well:

"Never ever discuss anything deep-sleep related in this thread. I do not make modifications to prevent sleep and 99% of deep sleep problems are application/ROM related. Discuss it in general section. I do not want any positive ("this kernel sleeps like a baby") or negative ("There is a big problem with deep sleep. Please fix it") messages in my development thread."

Still working on exFAT compatibility support (for stock ROM) without sacrificing kernel performance :) No boot menu on single ROM mode.
