Thank you for your advice.

But then, when I make bootable image (using this kernel and ramdisk from clockwork recovery), and load it with fastboot, strange thing happens... If I enter to fastboot mode from power off state by pressing "Back" and "Power" buttons, the kernel loads, Linux logo appears on the screen and in a few seconds the tablet turns off (kernel crash?). In contrast, if I enter fastboot mode when tablet is already ON by pressing "Back" and "Reset" buttons, the kernel boots and even runs init, starts adbd and recovery utlity from ramdisk. I could even use adb to get logs from dmesg and dump some /proc/* stuff to get the configurartion to compare it with one from working kernel. Nevertheless, the tablet turns of in a few minutes (another kernel crash?). Unfortunately, there are too many variables to find the working configuration in a short time, especially without knowledge wether some additional patches are necessary for this board or not. This is why I posted this question, just in case if someone has already found something... The global idea is to migrate to Android 2.3 or even 3.0 from 2.1 that I have and to add the ability to suspend to RAM to start faster from low power consumption mode. I think this is impossible with the original 2.6.29 kernel. Serguei. -- unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting
