Quoting Kyrre Ness Sjobak <kyrre solution-forge net>:
Try an ACPI suspend (echo "mem" > /sys/power/state), and see if you get the same error. I did (on a Dell Lattitude C600) a couple of weeks back. (rawhide)
Normally suspend to RAM leaves my notebook without vidio on reboot or it causes it to hang. I was more interested in the state of suspend to disk, actually. -- Bojan
