Backtrace from Xorg
reproduced on g45. Noted that the app only sets s/t wrap modes on cube mapping, but the docs claim that we need to have all 3 in the same mode or it gets angry. Smashing all 3 settings to CLAMP didn't help, though. The hang is on what is, at first glance, a perfectly healthy batchbuffer. (INTEL_DEBUG=bat,sync) I have a very similar issue on a box with a GA-EG45M-DS2H (G45) motherboard. The backtrace I see in xorg is different though and I also don't have any "[mi] EQ overflow" spam in my xorg.log. Once there is a patch for this, please post the commit sha1 or .patch and I will test it on my box as well. My bug is here: http://bugs.freedesktop.org/show_bug.cgi?id=20086 *** Bug 20086 has been marked as a duplicate of this bug. *** I can no longer reproduce this with Mesa master. Can anyone else test? If would be useful to understand when this got fixed (for potential cherry picking), I might try to bisect later (if I find the time) but if anyone got known good or known bad commits, please paste them here. I just tried Mesa 2305642b2e8edcebdc727f1181f7dbfcc78e8028 and it no longer causes a hang. Mass version move, cvs -> git |
