Version information: mesa-dri-drivers-7.8.1-8.fc13.x86_64 mesa-libGL-7.8.1-8.fc13.x86_64 Finally my i965 has a working mesa, previously it just segfaulted when trying to run cairo-gl. Don't see any hangs so far... With 0e49892ed0bd2c34c1c3461d38a409ae18bfdc64 from drm-intel-staging I still get a hang and the following is printed: [ 374.318024] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...

I should have used -next rather than -staging and the symptoms should really have been reported back in bug #30083... Sitsofe, thanks for testing again... I don't think I'm going to apply the domain fixup to -fixes since we so late in the cycle and this is an error path that we should not hit in the first place. Any chance you can try a more recent version of mesa? I've just tried a 32 bit Ubuntu 10.10 live cd which had the following packages: libgl1-mesa-dri 7.9~git20100924-0ubuntu2 libgl1-mesa-glx 7.9~git20100924-0ubuntu2 xserver-xorg 1:7.5+6ubuntu3 xserver-xorg-video-intel 2:2.12.0-1ubuntu5 linux-image-2.6.35-22-generic 2.6.35-22.33 and it had the same issue as described in comment #1. Still here in the latest Fedora 15 pre-pre-release. At first everything is frozen and then after a few seconds the screen goes black and stays black no matter what (the system still appears to be alive though). 00:02.0 VGA compatible controller [0300]: Intel Corporation 82G965 Integrated Graphics Controller [8086:29a2] (rev 02) Kernel: 2.6.38-0.rc6.git6.1.fc15.x86_64 xorg-x11-drv-intel-2.14.0-2.fc15.x86_64 xorg-x11-server-Xorg-1.9.99.1-6.20101201.fc15.x86_64 dmesg snippet to be attached.

Still here with rawhide on this t61 (965gm)... Rawhide with drm-intel-next, mesa.git and cairo.git (+ deps). WORKSFORME. :| Just recently I fixed mesa to handle the URB_FENCE erratum on 965GM. If we cross our fingers, that might just be the issue. And we also found a bug where HWS could only handle being allocated in the low 4GiB, and there is are further unfixed errata regarding handling of pages >4GiB by the i965. Do you have more than 4GiB and, if so, does mem=3g help? Can you try rawhide (or at least mesa.git and drm-intel-next) and grab a few i915_error_states if the hang persists? Thanks. > Do you have more than 4GiB No - this machine has 4GiB exactly. The previous results were from a LiveCD on http://download.fedora.redhat.com/pub/alt/nightly-composes/desktop/ which was probably rawhide (see http://www.mail-archive.com/fedora-devel-list@redhat.com/msg10108.html ). Unfortunately, due to the nature of the system in question I can compile and test later kernels but I can't switch anything in userland unless I boot temporarily to a LiveCD. I have tried a later kernel from drm-intel-next with the old Fedora 13 userland: Kernel: 2.6.38-rc7+ (47ae63e0c2e5fdb582d471dc906eb29be94c732f drm-intel-next) xorg-x11-drv-intel-2.11.0-5.fc13.x86_64 mesa-dri-drivers-7.8.2-1.fc13.x86_64 Output to be attached.

Hmm, still nothing obvious. We need to find a way of getting mesa.git onto your test machine so we can experiment. A very quick heads up: Testing with an Ubuntu Natty LiveCD with all the pieces updated to xorg-edgers and after pulling in goodness knows how many packages AND updating my cairo directory to the latest git version it ran the test fine. Unfortunately I don't know which piece fixed things. Versions: xserver-xorg-core 2:1.10.0+git20110307+server-1.10-branch.35503964-0ubuntu0sarvatt libgl1-mesa-dri 7.11.0+git20110316.b47d5084-0ubuntu0sarvatt libgl1-mesa-glx 7.10.1-0ubuntu2 linux-image-2.6.38-6-generic 2.6.38-6.34 libdrm-intel1 2.4.24+git20110307.3b04c736-0ubuntu0sarvatt xserver-xorg-video-intel 2:2.14.901+git20110316.ee740778-0ubuntu0sarvatt It looks like a newer versions of cairo can't trigger this problem on setups that have problems with the older cairo. I tried cairo.git on the previously mentioned Fedora 15 LiveCD and it caused a segfault in one of the i915 libraries (but X was seemingly unharmed). However, an older cairo caused the kernel errors and a lock-up. Newer cairo has also become much more difficult to test on older systems due to its dependency on a new pixman. I should also note that stock Ubuntu Natty alphas do not show the problem with a cairo.git but gcc refuses to compile my older cairo on Ubuntu Natty.

I can build debug kernel and do some debugging over ssh, what should I be looking for? Thanks, Andrey Andrey, it is highly unlikely you have the same bug, so please when you come to attach your error-state can you do so in new bug report. And can you include the full dmesg along with Xorg.log? Thanks. Sitosfe, I hope your still having fun. :) As we made no progress on identifying the crash scenario and it appears to have resolved itself by cairo doing things differently, I can only hope that the bug has been magically fixed with all the mesa/i965 work... |

Created attachment 38541 [details] dmesg output Description of the problem: When running cairo-perf-trace on the firefox-talos-svg benchmark X starts becoming slow before locking up completely on a desktop with a 965G. Lots of [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung messages appear in dmesg. The machine has to be rebooted to get a working X back - restarting X just results in a black screen with a cursor on top. Steps to reproduce: 1. Run CAIRO_TEST_TARGET=gl ./cairo-perf-trace -r -v -i3 benchmark/firefox-talos-svg Expected result: Benchmark to run to completion, X to be responsive throughout. Actual result: X becomes increasingly slower before becoming frozen with an unchanging picture on the screen. Messages like: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5 (awaiting 1820 at 1797) appear frequently in dmesg after the test starts.
