[Bug 43007] [savage] drm ERROR and hang after resume

[Tormod Volden]

Public bug reported:

Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
I have troubles with sleep/hibernation. Sometimes it hangs (completely,
not even sysrq works) just as it resumes, sometimes when I leave the
laptop for a while (can it be the screensaver?).

I enabled debug=1 for the drm module and ssh'ed from another computer.
The laptop doesn't have a serial port, so no serial console. I don't
know how to use a net console.

Just before the hang, this message appears:
[drm:savage_bci_wait_event_shadow] *ERROR* failed!
