Whenever something graphically intensive happens (except, apparently, video)
like compositing, a gpu lockup occurs, freezing X and even terminal switching
but allowing use of SysRq commands. Can sometimes switch terminals by first
pressing Alt-SysRq-K. Only occurs with an NV18 card; NV17 works fine, for
example.

I have enabled compositing in Metacity. One test was selecting the Applications
menu and rapidly switching through that and Places and System, which eventually
froze X. After doing Alt-SysRq-K, it allowed me to log back in, and I tried
again with no problem; I opened some semi-transparent terminals, enlarged them,
and moved them around over eachother. Trying to enlarge the ~eighth terminal
froze X. Eventually I had a kernel panic. Occasionally I can't even boot fully.
Sometimes X will freeze and allow cursor movement, other times won't. Has
occured a couple times in a (Ctrl-Alt-F1...) virtual terminal.

Often I see colorful flashing as textures load, particularly at boot. Once I
rebooted and seen the screen as it was when X froze, for a few seconds, and it
cleared and finished loading GNOME.

I suppose there is a chance the card is defective...but it has no problem with
the NVIDIA binary drivers. (As an aside, I even had Compiz running in Nouveau
for some durations before freezing.)

Can you reproduce without the 3d driver? E.g. after hiding
"/usr/lib/dri/nouveau_vieux_dri.so" somewhere the loader wouldn't look in.

The report on launchpad indicates that this is reproducible without the 3D
component installed.

Created an attachment (id=34310)
 --> (http://bugs.freedesktop.org/attachment.cgi?id=34310)
nv18_pgraph_lockup.patch

The attached patch might help, in any case we don't have an mmiotrace for this
card yet and it would be useful if we want to fix it properly.

In short, you'd need to:
- Start tracing
- Load nvidia.ko and start X up with the nvidia proprietary driver
- Run some 3d for a few seconds (e.g. fire up glxgears)
- Stop tracing and send the generated output to mmio.dumps at gmail.com

It's explained in more depth here:
