"Unhandled ustatus 3" means "FAULT" as best I can tell. And of course since gnome-shell also acts as a compositor, that means your display is shot. The question is how can this happen though... I guess something was requested to be migrated to vram and that request failed, but the driver didn't notice? Not sure. Your second log shows a pushbuf submission failure that caused a validate fail. I don't remember if that means that something was claimed to be in VRAM and wasn't or if it means that something was requested to be moved to vram and the move failed. The fact that you can even go to another TTY and restart GS indicates that the card is in no way hung, which is nice. You don't mention what version of mesa you're using... but I'm assuming something pretty recent, like 10.0.3 or maybe even 10.1-rc1? -- You are receiving this mail because: You are the assignee for the bug.
