Alexander Kops:
1) Could you please remove the kernel parameter "i915.enable_rc6=0", and any other non-default kernel parameters and keep it that way going forward? It is best to keep this as close to the default configurations as possible.
2) Could you please reproduce the problem with the latest mainline kernel, and attach to this report as separate files syslog and kernel.log?
3) Please advise which of the three events happened as per the Bug Description.
4) To satisfy a curiousity, does your computer's fan run loudly, and/or does the computer run hot temperature wise? Temperature monitoring information may be found at: https://help.ubuntu.com/community/SensorInstallHowto I would recommend polling only once every few seconds.
