See summary. I installed kernel-2.6.38.2-13.fc15.x86_64, booted it twice, it hard locked (cursor stuck, couldn't switch to a vt, couldn't ssh in) within ten minutes each time. Back to -9 and that hasn't locked in an hour of use, so I'm pretty sure it's the kernel. /var/log/messages doesn't have anything at the time of the lock, it just stops. I can try again with drm.debug if needed, but I know Ben has this same adapter so he may be able to reproduce easily.
I'm seeing the exact same thing (did not try to ssh in though) on my Dell latitude 6400 laptop with a Quadro NVS 160M (G98M), which is also an NV50 card and actually is pretty close to the 9400GT all around. I'm quite experienced with most forms of debugging let me know if there is anything I can do help. I'm hansg@freenode on irc.
Created attachment 490987 [details] Dmesg of lattitude 6400 + nvs160m
Created attachment 490988 [details] xorg.log of lattitude 6400 + nvs160m Note I believe I've been seeing this since 2.6.38.2-11 (-10 is doa, -9 is ok), but I did not file this bug before because I wasn't sure that this did not happen with -9. However I'm pretty confident now that this is a regression from -9. Note 2: The attached logs contains some vc / vt switches. This happens without them too, this was just me switching to a text vc to scp the logs away from the system, since sometimes it does not even get enough uptime to browse to a bug and attach logs (when running -13).

I've been running kernel 2.6.38-2.14: * Tue Apr 12 2011 Ben Skeggs <bskeggs> 2.6.38-2.14 - nouveau: correct lock ordering problem On the machine in question, with gnome-shell the entire day yesterday and I had 0 lockups, so it seems this fixes this, closing.
yeah, ditto.
