Hi Colin, 

Yes. please refer the
https://01.org/linuxgraphics/documentation/how-report-bugs for collecting log.

BTW for quickly checking, could you reproduce this issue (running "echo 0xe >
/sys/module/drm/parameters/debug" prior to issue reproduction) then doing
following things if not suffering system halt.

cat /sys/kernel/debug/dri/0/i915_error_state > ~/i915_error_state.log
dmesg > ~/dmesg.log

If system halted, please reboot then get "kern.log" (kernel message).

Finally, please always upload "kern.log" in folder "/var/log/" and
i915_error_state.log/dmesg.log (if not system halt). Thanks!

Because I don't have your docking system, it cannot reproduce it in my side and
need your detail of log further.
