Certainly there appears to be an issue in the xf86-video-nouveau EXA implementation when the card dies, it starts dereferencing NULL-ish pointers. However I think that the card dying is the primary issue... The bug here starts out with [ 6.760320] nouveau E[ DRM] GPU lockup - switching to software fbcon before anything really happens, and then X starts, and PGRAPH is variously freaking out. The nouveau GPU reset logic isn't so great... my experience is that oftentimes only a reboot really fixes a GPU lockup. (Sometimes it's fine though.) In the altlinux.org bug there's also a GPU lockup detected, and it's not likely to be due to the fact that X died, but rather the other way around. (Lockups aren't necessarily detected immediately...)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
