I have not any problem during flashing this kernel.
I root my phone using markolino63's method, the only thing that is
strange to me is that when i'm on cwm recovery and want to reboot
my phone i take this message "Rom may flash stock recovery on boot.Fix?
and i have to say every time "no" for rebooting...is that normal?

Same message in my recovery and a strange issue is that sometimes when I restore a backup from cwm it says that couldn´t restore data, but this is not always, I don´t understand how this is possible and if it could be related to something done wrong in the device when unlocking bootloader or rooting.

With jb? Why lelus?!

When I rooted my device, my bootloader wasn't unlocked. So I didn't find any other method. Now that I have unlocked my bootloader, I know there are easier methods :) .

So the way to root the phone doesn't seem to be the cause of those custom kernel panics. So what could be the cause ? :confused:

For the question that CWM Recovery asks on reboot after flashing a kernel, I also have it (I have it for the UMS mode activation through ZIP too).

Already tried. I think problem is other. I have manully add init.d support and also doesnt work. Used also uni init apk and doesnt work. Init.d support is there and all permissions are correct but nothing. For example, if you try zram script with terminal, not swap space is taken. So there is a problem also with that. I think there is something wrong in your source. Try to recompile from scratch. :thumbup:

To enable init.d support you can add these lines in init.rc:
Code:
service sysinit /system/bin/logwrapper /system/xbin/busybox run-parts /system/etc/init.d
    class main
    user root
    group shell
    oneshot
Busybox is needed.
That's the only thing I did on my kernel and it worked ;)

I have add manually my init.d support and doesnt work the same. There is a problem, different, in kernel.

i think he refers to a powered hub, it's like otg cable for razr (my previous device). check this video http://www.youtube.com/watch?v=Ax1RIuwRWhw , so my opinion is that it's useless 100 cables... just test my otg cable on l9, doesn't work on stock kernel and also on this one. it surely needs a powered hub.

Exactly, power hub. I dont remembered right expression :eek:

    I'm looking now for higher stable GPU frequency and voltage, very high freqs cost much battery life

    Ps. sorry for my bad english
