Revision 087fbc9962e10a65fb0b542ecfc116ebf6cf1735 authored by Andy Lutomirski on 13 May 2011, 16:14:54 UTC, committed by Linus Torvalds on 13 May 2011, 19:22:51 UTC
My Q67 / i7-2600 box has rev09 Sandy Bridge graphics. It hangs instantly when GNOME loads and it hangs so hard the reset button doesn't work. Setting i915.semaphore=0 fixes it. Semaphores were disabled in a1656b9090f7 ("drm/i915: Disable GPU semaphores by default") in 2.6.38 but were then re-enabled (by mistake?) by the merge 47ae63e0c2e5 ("Merge branch 'drm-intel-fixes' into drm-intel-next"). (It's worth noting that the offending change is i915_drv.c, which was not marked as a conflict - although a 'git show --cc' on the merge does show that neither parent had it set to 1) Signed-off-by: Andy Lutomirski <luto@mit.edu> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
