This bug seemed to become harder to trigger when I installed git-as-of- Oct-26, then easier again when I installed git-as-of-Nov-14, but given that this change seemed to persist after returning to 3.11 (suggesting a left-behind configuration change) and the general randomness of the bug, this would not give a reliable bisection (so the date mismatch doesn't rule out #71662 being the same bug).
In 3.8.0 the same symptoms occur but the log message is nouveau ![ PFIFO][0000:01:00.0] unhandled status 0x01000000 I suspect (but have not tested) that this change was http://cgit.freedesktop.org/nouveau/linux-2.6/commit/drivers/gpu/drm/nouveau/core/engine/fifo/nvc0.c?id=32256c87ead3edec86bed5023a0ff96a6d907931 ,i.e. this error was what is now the warning. Is 0x00800000 unhandled because it is an inherently fatal error, or because nobody outside Nvidia knows what it means? https://github.com/envytools/envytools/blob/master/hwdocs/fifo/nvc0-pfifo.rst is a contentless stub. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1243557 Title: [NVS 4200M] X freeze, "unhandled status 0x00800000" To manage notifications about this bug go to: https://bugs.launchpad.net/nouveau/+bug/1243557/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
