<pre>Man can notice :
ERROR: 0x00000105
TLB page fault error (GTT entry not valid)
Invalid page directory entry error
Cacheline containing a PD was marked as invalid
Can you try to update your kernel with latest drm-intel-nightly or linux
mailine (4.9.rc5) and see if this is still occuring?
Can you attach your kernel log (ie dmesg)? You may add "drm.debug=0x1e
log_buf_len=1M" in your boot command line to collect more debug data.</pre>
