Machine is running an up-to-date Fedora 17 and has a 9600GT card:

https://bugzilla.redhat.com/show_bug.cgi?id=850573

I have an LG 44NHM84 TV connected to the second DVI port of a GeForce 9600GT
card using a DVI-to-HDMI cable and an HDMI switcher. If I switch the switcher
for the TV to the computer input, the main monitor loses signal as well as the
TV, and dmesg reports the following:

Sep  8 23:12:54 newcastle kernel: [1467414.791946] detected fb_set_par error,
error code: -16
Sep  8 23:12:54 newcastle kernel: [1467417.024758] [drm] nouveau 0000:01:00.0:

Sep  8 23:12:57 newcastle kernel: [1467420.791069] [drm] nouveau 0000:01:00.0:

Xorg also segfaults with the following backtrace:
