drm/i915 crashes quite often here, today during Half-Life 2's intro:
[171527.464595] [drm] Reducing the compressed framebuffer size. This may lead to less power savings than a non-reduced-size. Try to increase stolen memory size if available in BIOS.
[172042.110000] [drm] GPU HANG: ecode 9:0:0x85dffffb, in hl2_linux , reason: Hang on rcs0, action: reset
[172042.110001] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[172042.110002] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[172042.110003] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[172042.110003] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

I currently can't attach /sys/class/drm/card0/error, bugs.freedesktop.org gives me an "Internal Server Error".

It seems bugs.freedesktop.org fails spectacularly if a to-be-uploaded file does not have read permissions for the user doing it.
This should be fixed by:

i965: Disable regular fast-clears (CCS_D) on gen9+
This partially reverts commit 3e57e9494c2279580ad6a83ab8c065d01e7e634e
which caused a bunch of GPU hangs on several Source titles. To date, we
have no clue why these hangs are actually happening. This undoes the
final effect of 3e57e9494c227 and gets us back to not hanging. Tested
with Team Fortress 2.

I can confirm that Mesa 18.104.22.168 (1:22.214.171.124-1~a~padoka0 from https://launchpad.net/~paulo-miguel-dias/+archive/ubuntu/pkppa) seems to fix the issue on Ubuntu 17.10 (amd64, Intel i7-6700HQ w/ Intel HD Graphics 530; Lenovo ThinkPad T460p).
