This is just a workaround which can make your system run without a hang until a proper fix is available. The downside is most likely worse performance.

http://bugzilla.opensuse.org/show_bug.cgi?id=955097 http://bugzilla.opensuse.org/show_bug.cgi?id=955097#c3 --- Comment #3 from Ronny Peine --- Hello again, what does you "cat /sys/module/i915/parameters/semaphores" give as root when you use the parameter at boot? If this says 0 than the workaround is implemented. If this isn't sufficient, you can try additionally the parameter i915.i915_enable_rc6=0 This disables the rc6 power saving. I had a similar bug with the intel drivers with openSUSE 12.3 which had a very similar problem. Maybe this will help you. You can check if both parameters are correctly set by checking the output of following commands as root, both should output 0: cat /sys/module/i915/parameters/semaphores cat /sys/module/i915/parameters/i915_enable_rc6 If the output does not say 0, you can set these parameters with a modprobe configuration: vi /etc/modprobe.d/99-local.conf [add following lines, edit mode with "i"] # Workaround for intel driver bugs options i915 semaphores=0 i915_enable_rc6=0 [save with ESC and ":x" ENTER] After this you maybe have to recreate the initrd image. On older openSUSE release the command "mkinitrd" had done this. I don't know how it is done with dracut. If you put a "#" before the options line, you can disable the workaround. Hope this helps you. Kind regards, Ronny (In reply to Michael Bütow from comment #2)

In the meantime i moved to Tumbleweed to have earlier access to the updates

Hello,

i missed the update from january - sorry for that

i tried the options but cannot activate the i915.enable_rc6 option

The modprobe - 99-local is now # # please add local extensions to this file #

options i915 semaphores=0 i915_enable_rc6=0 ^^^^^ Leave this out. It should be enable_rc6=0 in 99-local or i915.enable_rc6=0 on
