freezes during suspend

1) intrepid
2)
3) my computer shutsdown into suspend mode. including shutdown of fans and monitor, wakes up properly
4) what actually happens, compiz/gnome fades out, harddisk spins down, the rest of computer parts stay powered, a standard-output cursor/underscore keeps blinking.

Alt+right-key still changes console views, but can't login because normal keys aren't being registered. Only remedy is a hard-reset.

using nvidia-glx-177.80

Which logs will be of value?

/var/log/messages doesn't show anything besides networkmanager releasing ip's

Sorry for the rather long snippet
19:53:44 is the time on which I pressed the suspend option in gnome. 19:55 is the reboot sequence.
