weird last test in runlog is igt/gem_exec_suspend/basic-s3. 
igt at kms_pipe_crc_basic@suspend-read-crc-pipe-c is run a lot later.

igt/gem_exec_suspend/basic-s3 started:

...

Then basic-S4-devices is run, before s4 is finished there is error logs from
"ASIX AX88179 USB 3.0 Gigabit Ethernet":

So, I believe that there was a network issue, the machine kept running the
tests but the machine will rebooted by Jenkins loosing connection.

I.e. this is not a i915 issue.
