           Summary: [NV94] X hangs, logs show kernel: nouveau E[

                    followed by an X trace

I just upgraded my desktop to Fedora Rawhide, and since then X has twice
crashed with the same symptoms. Oddly, I was using kernel 3.18 from
kernel-rawhide-nodebug before upgrading from F21 to Rawhide, and 21 and Rawhide
seem to have similar versions of the nouveau driver and Xorg components, so I'm
not sure what's changed - libdrm or mesa, perhaps?

Anyway, the non-debug log I have so far is:

Dec 11 11:44:13 adam.happyassassin.net gdm-Xorg-:0[1540]: (EE) [mi] These
backtraces from mieqEnqueue may point to a culprit higher up the stack.

then there's a bunch of similar X traces, I'll attach the whole thing. I'll try
and get drm.debug logs and attach those also.

There is one EE line during initial X start:

Dec 11 10:52:16 adam.happyassassin.net gdm-Xorg-:0[1540]: (EE) NOUVEAU(0):
[COPY] failed to allocate class.

but that line seems to be present in older boots where I didn't encounter this
problem, too.

I'm running GNOME Shell and have dual monitors attached to DVI, in portrait
orientation.
