I have FC2 installed on a Thinkpad T41. I turned off ACPI support in the kernel to get suspend working (acpi=off in the boot options). The laptop does reliably suspend.
Unfortunately, suspend is only half the story. When I resume, GNOME 2.6 sometimes hangs after trying, for some reason, to generate screen shots. This occurs about 25% of the time. The CPU pegs when this happens. Occasionally this sequence is successful and I can get control back after completing a couple of "save screenshot" dialogues. Usually, though, I end up having to kill X to get control back. Even when I don't have to kill X, it's sometimes the case that the keyboard is dead and some mouse functionality is missing.
I can work around all of this by remapping the printscreen key. That's kind of an ugly hack, though. I'd rather fix the problem (whatever it is).
So... What's wrong? Suggestions most appreciated...
ps: Oh - this doesn't seem to happen with KDE. As far as I can tell, it's GNOME-specific.
