When using modesetting and a recent kernel (errors below are from 2.6.33-rc4, but also occur with 2.6.33.0) and xorg (I can't give an exact xorg version), after some time (about 930 seconds in the dmesgs i've pasted but it varies) the screen jumps to the left (and wraps around using pacman like rules). Possibly relevant is that im using kde4.4 with desktop effects. It takes a while to reproduce, but it does happen every boot eventually. version numbers xserver-xorg 1:7.4+3ubuntu10 xserver-xorg-core 2:1.6.5+git20091107+server-1.6-branch.2dbcb06a-0ubuntu0sarvatt~karmic xserver-xorg-video-all 1:7.4+3ubuntu10 xserver-xorg-video-ati 1:6.12.99+git20100120.30a19b75-0ubuntu0sarvatt~karmic xserver-xorg-video-radeon 1:6.12.99+git20100120.30a19b75-0ubuntu0sarvatt~karmic kernel 2.6.33-rc4 (x86_64) An example dmesg (I have more i can attach if they will be useful): [ 937.923082] [drm:radeon_fence_wait] *ERROR* fence(ffff880055f0cc40:0x0004E051) 510ms timeout going to reset GPU [ 937.924501] [drm:r300_ga_reset] *ERROR* VAP & CP still busy (RBBM_STATUS=0x8400C100) [ 938.078474] [drm:r300_ga_reset] *ERROR* Failed to reset GA !

Created attachment 35088 [details] kern.log from complete session including schedule IB errors Same here, with an RV505 CE (Radeon X1550 64-bit).

Created attachment 35089 [details] Xorg.0.log from the same session No messages in the Xorg.log, so driver seems to be fine. Will test that with a recent 2.6.34 candidate to make sure it still is a problem.
Created attachment 37589 [details] Lockup with 2.6.35 I'm getting this with 2.6.35, libdrm 2.4.21, xf86-video-radeon 6.13.1, Mesa 7.8.2 (I'm not using the Gallium driver yet, but the "classic" one) and X.org server 1.7.7. Please let me know, if you need further/other information and I try to provide it.
Oh, just forgot to note it: the GPU in question is a R300 (Radeon 9500 Pro).

Is this a regression? If so what parts did you upgrade and what versions were you using when it last worked?
(In reply to comment #5) > Is this a regression? If so what parts did you upgrade and what versions were > you using when it last worked? For me it seems to be. I've only updated the kernel from 2.6.34.1 to 2.6.35.

I've only updated the kernel from 2.6.34.1 to 2.6.35. Can you bisect between 2.6.34 and 2.6.35 to see what commit is causing the problem?
(In reply to comment #7) > Can you bisect between 2.6.34 and 2.6.35 to see what commit is causing the > problem? I can try, though I can give you no estimate how long this will take, as I haven't found a way to repeatedly trigger the lock-up. I'm now on 2.6.35 for over two hours again and nothing happened. While it took me only 30 minutes before that to hit the lock-up.
I'm seeing this too, this also seems to be the same bug as: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/586243/ https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/619365/ Everything works mostly fine for me, until I go to redhat's bugzilla which has the dotted tile background (which has caused issues before) and scroll around a bit, then my screen goes black for a couple of seconds and comes back distorted. Usually it is shift to the right by 200 pixels or so, the mouse cursor is corrupted and other then that thinks don't work. I've also had a couple of cases where some corruption was happening but I could still type and see what I typed in plain old xterm (but not in firefox) I could select text in firefox, it was not being highlighted but pasting worked, which was good as that meant I could copy and paste and then save a long bz comment I was typing :) My syslogs fills with: host kernel: [drm:radeon_cs_ioctl] *ERROR* Faild to schedule IB ! host kernel: [drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule IB(5). host kernel: [drm:radeon_cs_ioctl] *ERROR* Faild to schedule IB ! host kernel: [drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule IB(6). host kernel: [drm:radeon_cs_ioctl] *ERROR* Faild to schedule IB ! host kernel: [drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule IB(7). host kernel: [drm:radeon_cs_ioctl] *ERROR* Faild to schedule IB ! host kernel: [drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule IB(8). host kernel: [drm:radeon_cs_ioctl] *ERROR* Faild to schedule IB ! host kernel: [drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule IB(9). host kernel: [drm:radeon_cs_ioctl] *ERROR* Faild to schedule IB !

Created attachment 40633 [details] Excerpt from /var/log/syslog for 2.6.36.1 The above gets logged now to syslog when the lockup happens (the "couldn't schedule IB(…)" part continues endlessly (until I killed KDM) after the line I cut off, but I thought one iteration is enough). Unfortunately I deleted the rescued Xorg.0.log which had additional information. From what I can remember: it looked like what Eric posted in comment #12, though I had two backtraces there, one over the line "(II) AIGLX: Suspending AIGLX clients for VT switch", which was about 20 to 30 lines long and then something that was like the part posted in comment #12. The software versions used are: Kernel: 2.6.36.1 DDX: 6.13.2 Mesa: 7.9 libdrm2: 2.4.22
Created attachment 40634 [details] Excerpt from /var/log/kdm.log Ha, I found that longer backtrace: it got also dumped in /var/log/kdm.log; in the hope it helps (the shorter one is still missing, but again: IIRC it looked like what Eric posted in comment #12).
