Bug 13778

After playing around with rotation on my NV31 (drivers rebuilt today from latest git) I got and DMA-queue hang. It occured while I was minimizing windows to a panel in gnome. The pixture froze (the mouse still moving) and gdm restarted X.
The intresting part here may be that when I reached the loginscreen I had the same problems as before the fix for NV31 with missing fonts.
A "sudo /etc/ini.d/xdm restart" was needed for that to fix itself. Starting firefox-3 and starting to typ bugzill.. it hang again (could be due to the massive graphics in firefox-3s history-bar).

Both where Class 0x0397 and Mthd 1808... dmesg one crash (identical dmesg) is attached with Xlog from both.

xorg-server-1.4.0.90
mesa, x11-drm, libdrm and nouveau fresh from git.
