Dump of dmesg

I got a GPU HANG when leaving the laptop idle with an external Thunderbolt
monitor connected via the USB-C port. This time I was able to SSH into the
machine and get the error state out, will try to reproduce it again.

I'm running a kernel build I have compiled today from drm-tip, the latest
commit in the tree for me is:

    drm-tip: 2017y-08m-14d-09h-26m-51s UTC integration manifest

I'm running Ubuntu on a Dell Precision 5510 with 4.13.0-rc4+ x86_64. It's an
Intel GPU machine with:

00:02.0 VGA compatible controller: Intel Corporation HD Graphics P530 (rev 06)

Just recently I have updated the BIOS to the latest version, 1.2.29, but it
doesn't seem to be related:

I'm attaching full dmesg and the error state to this bug, but I haven't been
running the machine with drm.debug=0x1e. Please let me know if I need to do
that.
