Created attachment 343670 [details] dmesg (w/o the final message from radeon_gem_ib_get) Description of problem: X hangs. The OS stays up, but needs to be rebooted since X is hard hung. This occured after a significant uptime, a couple of days. Version-Release number of selected component (if applicable): kernel-2.6.29.2-126.fc11.x86_64 xorg-x11-drv-ati-6.12.2-13.fc11.x86_64 xorg-x11-server-Xorg-1.6.1-11.fc11.x86_64 How reproducible: Unknown, probably not very easy. Steps to Reproduce: 1. Use the system normally, do not reboot for a couple of days Actual results: Hang of X Expected results: Working normally Additional info: Previous xorg-x11-drv-ati was 6.12.2-9, possibly worked ok on same kernel, but perhaps it's a question of uptime.

I'm attaching the actual dmesg without the message just in case someone wants to see interrupt layout etc.
Oh never mind, it's a dup of bug 493068. *** This bug has been marked as a duplicate of bug 493068 ***
