@kamal - Thanks for all of your hard work on this issue. Unfortunately, it doesn't look like your patch resolves the issue on a Dell Inspiron 600m. After updating my system as described, I still cannot resume from suspend. The disk spins up but the screen does not come back and I have to do a hard reset.
FYI - Just to make sure I have installed the fix correctly, here is the kernel signature from dmesg: [ 0.000000] Linux version 2.6.32-22-generic (bui...@einsteinium) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) #34~pre201005061001-Ubuntu SMP Thu May 6 18:37:25 UTC 2010 (Ubuntu 2.6.32-22.34~pre201005061001-generic 2.6.32.11+drm33.2) Should I open a new bug report or continue to use this one?
