Description of problem: Xserver restarts very often when I resize application windows. Most often this happens when I have several windows opened and I resize Firefox window. I am able to crash the server under a minute, just by resizing.

I am running from that LiveCD, so I don't have any custom xorg.conf. I have booted with "drm.debug=14 log_buf_len=16M" boot options as suggested at http://fedoraproject.org/wiki/How_to_debug_Xorg_problems. Do you need some further information?
Can you post /var/log/Xorg.0.log.old from after an X restart please :)

Created attachment 482077 [details] Xorg.0.log.old I continue to hit the same crash reported in comment#7. This hits randomly minutes after I start the desktop ... and has occurred about 6 times in the last 20 minutes. With the following packages: * xorg-x11-drv-nouveau-0.0.16-20.20110224gitbc5dec2.fc15.x86_64 * kernel-2.6.38-0.rc6.git6.1.fc15.x86_64 * xorg-x11-server-Xorg-1.9.99.1-6.20101201.fc15.x86_64 And the following nVidia adapter: * 02:00.0 VGA compatible controller: nVidia Corporation C79 [GeForce 9400M] (rev b1)
Can you update to http://koji.fedoraproject.org/koji/buildinfo?buildID=232757 (kernel-2.6.38-0.rc8.git0.2.fc15) and retry? Also, xorg-x11-drv-nouveau-0.0.16-22 (should be in updates-testing) will prevent the X server crash in these situations, and the error will be propagated to the client instead.
With nightly compose LiveCD containing kernel-2.6.38-1.fc15.x86_64 xorg-x11-drv-nouveau-0.0.16-23.20110303git92db2bc.fc15.x86_64 I am unable to crash Xorg by resizing windows. Problem seems fixed. Closing this report. James, can you verify, if you have time? Thanks.
