Hi,

w/ 2.6.36 I also had major suspend/hibernate problems. Lately, that was an issue on LKML too http://kerneltrap.org/mailarchive/linux-kernel/2010/10/27/4638146 . Further, I had apparmor seg faults w/ the stock 2.6.36 LK.

As written in bug 666172 (marked as duplicated of this one here)
echo (disk|mem) >| /sys/power/state
always worked fine for me. However, from time to time I get Kernel Ooopsies using the Ubuntu Kernel. I attach 2 dmesg traces here showing that. I did "short-cut" the /usr/lib/pm-utils/bin/pm-action script to skip everything (hooks) but the suspend/hibernate action.

Currently, I'm trying the 2.6.35 stock kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.35-maverick/ It's too early to say if it also ooopses since that happens only once in a while. suspend/hibernate seems to be stable though.

/var/log/pm-suspend.log has never shown any issues. Just ended w/ the hooks section.
