Bug Description
Since trying out Maverick Alpha, my Thinkpad T41 quite often (approx. 5 out of 10 times) freezes while entering hibernation mode. It always happens at the same stage. When hibernating successfully, this happens:
1. session gets locked, screen black, backlight on
2. VT appears, "moon" LED starts blinking
3. Backlight is turned off, "moon" LED blinks
4. Backlight is turned on again, "moon" LED off, HD saves memory contents
5. Computer turns off.
When the bug hits, computer hangs at step 3. (I once waited for some 15 minutes, nothing else happened.)

I tested several mainline kernels (last is 2.6.36-
