So folks, its a little bit too late, i know:o, but i made a flashable zip of stock kernel from the China FW. It contains all the necessary modules, etc.. It contains all the necessary files that the tab falls to sleep after l2_hsic going crazy. This solve the unnecessarily high battery drain since Android 4.0.4 aka ICS was published by samsung. Is intended for those who have no desire to a custom kernel. ;)
But notice this kernel is not overclockable, should work with any firmware and this requires root to flash the kernel.
PS: But this kernel is only for the 3G versions (GT-P7500/7501), why only the 3G models are equipped with the high battery drain.
What do I need?

How do i flash the kernel?

PPS: I testet it with the Hungary FW without this kernel. After 1 hour the bug came back.:silly: So i flashed this kernel again and it works like charme. So it should work with any other FW.

- The kernel - Root ->look here -> Do you have ICS on it, point ranges 2 and 3 -> You still have Honeycomb on it, start from step 1 - a custom recovery -> for example here - wherewithal basic knowledge -> Look at the forum or ask at Aunt Google.

- download the kernel and flash it through your custom recovery - Of course only interesting if you are already using TWRP or CMW.

Flash through CWM / TWRP

You place the zip on the internal memory or external SD card. - To boot into recovery, hold volume down when you restart - Go to "install zip from sd card", depending on the type of recovery (CWM) -> Or just install (in TWRP) - look for the folder where you have placed the zip - And flashes this now by clicking on yes in CMW or slide to the right with TWRP. - Then reboot and kernel you got it. |

Before you flash this stuff, made a backup (Nandroid) of your system. Only if something goes wrong, this make sure you can restore your old system again. I 've tested it, but you never know.
