           Summary: radeon lockup on resume
           Product: DRI
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: hramrach@gmail.com


The card locked up after resume from suspend.

The resume probably happened because suspend failed and  the system did not
shut down at all meaning  the card was not reset to text mode.

Initializing radeon from anything but text mode fails but normally does not
lock up the card completely.

What card is this?  Can you attach your boot up dmesg?  Is this a regression? 
If so when did it last work and can you bisect?

I don't understand how you can get "GPU lockup" messages from
radeon_fence_wait(), but none from r100_gpu_cp_is_lockup()... Do you have
dev_err() output disabled somehow?

It's a redwood.

The bootup dmesg is below the locup messages.

I am not sure what dev_err() would be.

And now I rebooted and tried to kill Xorg with suspend and it would not lock up
the card, only keep resetting it.

hmm, I it looks like the driver resets the card quite a few  times over some
hours until it locks up permanently (or at least long enough for the next reset
to fail) or the driver gives up and the screen stays blank.

this is AFAIK an issue since introduction of KMS on r300, not a regression.

All my r300 works fine with KMS (and i have a lot of them), you just an unlucky
user. Not all r300 are affected, it's most likely the combination of your gpu
with your motherboard.
