Title:
Computer often freezes while entering hibernation since maverick alpha
Status in Linux:
Expired
Status in linux package in Ubuntu:
Won't Fix
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.)
/var/log/pm-suspend.log always ends with lines like these:
Tue Aug 24 20:46:55 CEST 2010: performing hibernate
I turned on pm_trace; the hw clock is set but after booting, there is
*never* a "hash matches" entry in dmesg output.
I tested several mainline kernels (last is 2.6.36-999.201008190908),
all show the same behaviour.
