--- Comment #1 from Andrew Travneff <travneff at gmail.com> ---
Seems like I have same for a long time at NV43. Now happens 1-2 times a day,
very annoying. VT works after that, but reboot is necessary to launch X again.

Affected kernels are at least 3.6 .. 3.11. However it was much better before I
updated Fedora 18 -> 19. 3.11 seems the worst case since it adds much more
freeze and errors messages like "BUG: soft lockup - CPU#0 stuck for a ...".

Proprietary driver periodically prints errors after some desktop freeze. Can it
be a dying HW?

Debug kernel also prints a note about "possible circular locking dependency" in
drm / nouveau.

Reproducible with launching "Savage: Rebirth" game. I haven't tried another 3D
games, but use KDE desktop effects.

Also a render artefacts are shown sometimes, mostly in Firefox.

Besides that, is there a GPU recovery feature in Nouveau? What happened with
these patches: [3]?
