I'm seeing problems with resume (using s2ram) on thinkpad z60m notebook with
very fresh git kernel (built yesterday). It looks like this - I get screen
resumed with X window running on it, I see mouse pointer but pointer doesn't
react to movement and sysrq keys also don't respond (tried to
umount+sync+reboot via sysrq).
The hangs doesn't always happen but it happens quite often (often enough to
get kmail trashed several times).
The problem is also happening on 2.6.26 kernels (I wasn't testing .26 too
much).
Now I'm back on 2.6.25 where the problem doesn't occur.
I didn't see any reports related to that on lkml which is bad thing 8)
Any ideas?

Not really. We must have broken something in 2.6.26, but there were not too
many suspend-specific patches in there vs .25.
What s2ram options are used?
What hardware is there in the box (chipset, graphics)?
Thanks,
Rafael

Ok, will get back to the problem when I get/notice something that can get us a
clue.

So here I am. Not directly resume hang but may be related. git kernel from ~2
days ago.
resume succeeded but dmesg indicated tons of:

Hm, cifsd. It is kind of known to have problems.
How reproducible is this?
