Kernel log

When using nouveau on Nvidia GeForce 580 GTX PC freezes. No reaction on keyboard only mouse pointer can move. Sometimes mouse pointer is not reacting too. It happens for a random time and in random activity, most often 10 sec - 2 min.
But if I set "nomodeset" option in kernel boot parameters the system is working fine without freezes.
This problem is actual for X.Org and Mir (Ubuntu-Next 14.10 x64) display servers.
Tested on Ubuntu 14.10 x64, kernel 3.16. But problem is actual for all versions of Ubuntu with Nouveau.

There's a known issue with NVC8's whereby there's some unknown deficiency in the nouveau ctxsw firmware causes most of those cards to hang. If the issue goes away when you use blob firmware (see http://nouveau.freedesktop.org/wiki/VideoAcceleration/#firmware for an easy way to get that set up -- you'll also need to add nouveau.config=NvGrUseFW=1 to the kernel cmdline) then you have the same issue as bug 54437.

Reopening this bug as an advice given by Christopher M. Penalver from Lauchpad
Comment 4 Ilia Mirkin 2014-07-22 11:05:13 UTC
Have you verified that your issue is fixed by using blob firmware? Once you do, makes sense to close this bug and mark it as a dup of the older issue.
Comment 5 Dmitriy 2014-07-22 11:08:24 UTC
Yes, blob firmware is working fine
Comment 6 Ilia Mirkin 2014-07-22 11:12:16 UTC
Not sure why you were given that advice on launchpad. The bugs are dups of each other (and older one wins). Should the other bug be resolved and you *still* have issues, you can open a new one. Until then...
