Once every day or so my system practically hangs (gets extremely unresponsive; X unusable; only SysRq magic working) while using Xorg with the nouveau driver (version 1.0.10).
I am running Debian GNU/Linux testing (jessie) with
$ uname -r
$ lspci | grep VGA
05:00.0 VGA compatible controller: NVIDIA Corporation NV40 [GeForce 6800 GT/GTO/Ultra] (rev a2)
This problem did not occur when I ran Debian stable (with nouveau).
When the system (practically) hangs, I get messages like this:
... GPU lockup - switching to software fbcon
nouveau E [Xorg] failed to idle channel 0xcccc0000 [ ...
Full dmesg would be great, esp the messages that led up to the GPU lockup. If you have libvdpau_nouveau.so installed, try removing it, that has been reported to cause issues on nv4x's.
I am afraid that I have not saved the Xorg log with these messages (of the crash). Moreover, I have not experienced crashes since my bug report.
I had not installed libvdpau_nouveau.so, but I did have libvdpau.so as a dependency of the mplayer2 package. Is this the same thing? I removed it and after that reinstalled it. Possibly the library is different from before, since before I used the debian-multimedia repository which may have contained this library, but not anymore since that repo has become obsolete for Debian.
I will report again when the problem returns. If I will not report within two weeks or so, we should close this bug report.
Forget most of my previous message. It now appears to be the case that I have crashes in combination with certain kernel:
3.7-trunk-amd64 no problem
As soon as I have an Xorg log with the error, I will post it here.
