Intel guys?
this is the sort of thing that is dropping between cracks.
Please follow up on bug reports.
Dave.
I have been experiencing problems with suspend/resume on my ThinkPad x60 for some time (sorry for being vague, I forget when it started). With 3.1 it seems to behave much better (no crashes).
The problems I'm still seeing is that sometimes the computer does not suspend when closing the lid, but manually using "pm-suspend" always works. Opening the lid again after a failed suspend causes it to flicker briefly and then continue working as before.
I receive the following warning in dmesg (after both successful and unsuccessful suspends):

The kernel is mostly unpatched, but the few patches it has (as well as its .config) can be found here: http://projects.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/linux.
Please let me know if you require more information.
Thanks for your time,
