Summary: seem to need to revert 213d9417fec62ef4c3675621b9364a667954d4dd to fix resume from hibernation. Bugzilla entry created: http://bugzilla.kernel.org/show_bug.cgi?id=12713 On kernel 2.6.29-rc3 and earlier, suspend/resume from disk (hibernation) works fine on my T60p with dm crypt full disk encryption. Starting with 2.6.29-rc4, I get hangs on resume from suspend to disk. On resume, after a bit of regular activity, the disk LED lights up with an unusual dull color and stays that way. Pressing CTRL-ALT-DEL causes linux to print a message that it will reboot, and reboot after a couple of seconds. I bisected and got to the following commit: commit 213d9417fec62ef4c3675621b9364a667954d4dd Author: Jens Axboe <jens.axboe@xxxxxxxxxx> Date: Tue Jan 6 09:16:05 2009 +0100 block: seperate bio/request unplug and sync bits Signed-off-by: Jens Axboe <jens.axboe@xxxxxxxxxx> I reverted the commit 213d9417fec62ef4c3675621b9364a667954d4dd on top of 2.6.29-rc5 (resolving a trivial conflict) and verified that reverting this commit fixes hibernate for me.
