Description Tobias Klausmann 2015-05-11 16:12:07 UTC
With libdrm 2.4.61 the X server segfaults with xf86-video-intel (.917) and X server 1.17.1!

i have bisected libdrm back to commit 8576527cfacaf42af8316e1030c192193e94225a - intel: Merge latest i915_drm.h.
reverse applying the patch on top of .61 works just fine as well.

Save yourself from more bugreports and release another snapshot...! :)

That may be a bit problematic, if i do --enalbe-debug on the driver, the bug is gone as well. If thats not necessary, i'll sure add one.
