Unfortunately, an hour later, apport catapulted me back onto this site. So this is with the 3.8.2 kernel and with the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.semaphores=0 i195.i915_enable_rc6=0"
in grub.

This time, I cannot find any error messages relating to i915 in the syslog or kernel.log. Not sure why apport sent me to this site here again. I now remembered that I installed some extension to apport in order to help capture kernel errors. All these error reports are generated by /usr/share/apport/apport-gpu-error-intel.py. It contains the line:
attach_file_if_exists(report, '/sys/kernel/debug/dri/0/i915_error_state', 'i
915_error_state')

Unfortunately:
root@machine:/usr/share/apport# more /sys/kernel/debug/dri/0/i915_error_state
no error state collected

Any more ideas how I could shed light into this? Otherwise I'll have to try a clean install in the coming days.
