It's significantly more than several times a day but not quite continuous. If you indeed have this bug, that should stop the lockups from happening. Irrespective, please file a new bug report so your hardware may be tracked. WORKAROUND: Edit your /etc/default/grub from: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.semaphores=0" run the following and reboot: sudo update-grub The side effects of this is rendering throughput is dropped by 10% with SNA, or as much as 3x with UXA. OpenGL performance is likely to be reduced by about 30%. More CPU time is spent waiting for the GPU with rc6 disabled, so increased power consumption.
