[Galaxy Tab 8.9 Android Development] C-o-M:
Using some kind of stock kernel, it doesn't reboot immediately. Whilst it starts with the same error message, it seems to enter sleep successfully. But right after then it tries to resume and fails:

see kmsg-samsung.txt

Another interesting log: When I connect to the PC right after it entered sleep, the screen goes on, but stays dark and doesn't react. But it's still accessible via adb and I get the following logcat:
