          Priority: medium
            Bug ID: 77892
          Assignee: dri-devel@lists.freedesktop.org
           Summary: [RV635] when GPU locks up, reset happens but X is
                    unresponsive except mouse
          Severity: critical
    Classification: Unclassified
                OS: Linux (All)
          Reporter: shawn.starr@rogers.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: unspecified
         Component: DRM/Radeon
           Product: DRI

For a long time now, I don't recall which 3.x broke this but there's been many
changes since and now, when the GPU does randomly reset, the display goes
blank, X display is restored, but I can only move mouse, cannot interact with
X.

Can someone point me to some debugging approaches to see if there's some lock
being held somewhere thats causing this?

I am able to ssh into the laptop so, this seems to point to some sort of lock
thats not released.

Bisecting radeon drm will be difficult if I have to start from near the
beginning of r600g drm support.
