| Summary | [RV635] when GPU locks up, reset happens but X is unresponsive except mouse |
| Severity | critical |
| Classification | Unclassified |
| OS | Linux (All) |

| 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.
