           Summary: [NV46] GPU lockup - switching to software fbcon
        QA Contact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: jesus.guerrero.botella-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: unspecified
         Component: Driver/nouveau
           Product: xorg

The GPU is this one:

01:00.0 VGA compatible controller: NVIDIA Corporation G72M [Quadro NVS
110M/GeForce Go 7300] (rev a1)

The thing goes as follows:

1) I run "mplayer <random video file>", I have tried mkv and regular divx or
mpeg video files, also youtube videos via the youtube-viewer tool, which uses
mplayer as a backend to play youtube videos. The result is always the same,
with independence of the video type.

2) The laptop seems to hang. However, I can still move the mouse. No element in
the UI reacts though.

3) If I wait enough time, I am suddenly thrown out to the VT, the pc still
seems quite laggy. Eventually, it recovers and I can write commands into the
VT.

4) At the end of dmesg I can see by now this output:

5) In the X log I can see this:

(EE) [mi] These backtraces from mieqEnqueue may point to a culprit higher up
the stack.
(EE) [mi] mieq is *NOT* the cause.  It is a victim.

=================================

This is on Gentoo, with kernel 3.15.0 (but it also happened with 3.14.5. The
arch is amd64. I am using nouveau 1.0.10, mesa 10.0.4, libdrm 2.4.52 and
(probably irrelevant) mplayer 1.1.1.

The kernel is unpatched, from kernel.org (no Gentoo stuff nor anything like
that).

Since I've seen several messages around the net about old kernel versions, and
they eventually got fixed by a kernel update, I guess this is a good candidate
for a regression. But to confirm that I will have to find an older kernel
version that works. That might take some time.
