Hi!
On my Thinkpad T500 with Debian-compiled kernel 2.6.35~rc6-1~experimental.1,
I still get OOpses on suspend.
The following OOPS has been found be using the platform method. I had to
hard-reboot as SysRQ didn't work. (although I have also seen similar suspend
OOPSes where it worked). The suspend has been initiated by echo disk >
/sys/power/state from virtual terminal.
http://wserver.wm1.at/~willi/linux/suspend_issue/suspend_error.jpg
However, I don't get the same OOPS every time, and the problem does not
occur at every suspend. I haven't managed to get more than one suspend
successfully finished (since a cold-boot). Particularly, it seems that if
the first suspend succeeds, the problem always occurs at the second attempt.
Also note that if I initiated the suspend from X, I often got a blank screen
(except for a blinking cursor) instead of the OOPS. (The fact that the
screen was blank could also be related to the fact that when tested from X,
I hadn't raised the log levels)
When I disable the i915 module (I renamed it), I can't reproduce the
problem.

Did it happen with 2.6.34 or previous kernels?
