Comment # 1 on bug 954188 from Takashi Iwai

Could you check whether the problem still exists on linux-next?   The kernel
package is available at OBS Kernel:linux-next repo.  4.3 seems to have a few
known issues on i915, unfortunately.

In anyway, care to report this rather to upstream?  At best, report it on
bugzilla.freedesktop.org category DRI/Intel.  Attach the whole dmesg output
there.  Also, boot with drm.debug=0x0e and attach the dmesg output again.
