Created attachment 701608 [details] Xorg.0.log / dmesg-stracktrace-elided.txt messages-extract.txt Description of problem: Running a system updated just today, I have a problem very similar to 849347 (883536 / 910559) and probably related to 843586 and 901984 ; based on comments in 849347 I understand we are operating "one bug per person" so I am filing this separately to help resolve the problem. When I switch console then my server crashes; the screen repeatedly flashes; I cannot use any key; I cannot switch console; I cannot reboot. If I activate magic sysrq then do fn-alt-sysrq-<release-fn>-k then I can kill the x server and my screen recovers. N.B. I seem to have the latest version of the driver described in 849347 (see version info below) Version-Release number of selected component (if applicable): Name : xorg-x11-drv-ati Version : 7.0.0 Release : 0.8.20121015gitbd9e2c064.fc18 How reproducible: almost every time. Steps to Reproduce: 1. ctrl-alt-f2 2. ctrl-alt-f1 3. repeat 1&2 if needed (never seems more than twice) Actual results: screen flashes white; then goes black; cycle repeats approx every second. Expected results: return to X server and see normal Fedora GUI. Additional info: nothing much visible in X server log (which I will attach) /var/log/messages shows [drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation -35! I am attaching X server log + dmesg (without stacktraces when I tested the magic sysrq) + relevant part of messages log.
Just restate the other bug numbers with hashes Bug #849347 and #901984 to try to get the links to work. I should make the note that the same problem also happens almost 100% of the time in a suspend / resume cycle or after a hybernate.
Please update ddx to xorg-x11-drv-ati-7.0.0-0.9.20121015gitbd9e2c064.fc18 it will fix your issue
Note that according to your first comment you have : xorg-x11-drv-ati-7.0.0-0.8.20121015gitbd9e2c064.fc18 not | xorg-x11-drv-ati-7.0.0-0.9.20121015gitbd9e2c064.fc18
Closing reopen if you still have the issue with xorg-x11-drv-ati-7.0.0-0.9.20121015gitbd9e2c064.fc18 or newer
What is wierd is that my problem has gone away but I still have Name : xorg-x11-drv-ati Version : 7.0.0 Release : 0.8.20121015gitbd9e2c064.fc18 sudo egrep 'kernel|xorg' /var/log/yum.log | sed -n '/Feb 23/,$p' shows Feb 23 01:35:40 Updated: xorg-x11-drv-intel-2.21.2-1.fc18.x86_64 Feb 23 08:06:28 Updated: xorg-x11-xkb-utils-7.7-5.fc18.x86_64 Feb 23 08:07:27 Updated: xorg-x11-server-utils-7.5-16.fc18.x86_64 Feb 23 08:07:39 Updated: kernel-headers-3.7.9-201.fc18.x86_64 Feb 23 08:08:08 Installed: kernel-3.7.9-201.fc18.x86_64 Feb 24 01:53:36 Installed: xorg-x11-drv-modesetting-0.6.0-1.fc18.x86_64 Feb 26 23:49:11 Updated: xorg-x11-server-common-1.13.2-4.fc18.x86_64 Feb 26 23:49:41 Updated: xorg-x11-server-Xorg-1.13.2-4.fc18.x86_64 Feb 26 23:49:43 Updated: xorg-x11-server-Xephyr-1.13.2-4.fc18.x86_64 so I guess the fix is actually in one of these. Anyway; it's fixed so I am happy.
