--- Comment #93 from Yves-Alexis <corsac at debian.org> ---
I just had a chance to test 4.18 and I have to say it's *not* fixed. Maybe it's
a different bug, but in any case I had a “soft” freeze with following message
in dmesg:

Aug 29 19:04:24 scapa kernel: [ 33.831280] [drm] GPU hangs can indicate a bug
anywhere in the entire gfx stack, including userspace.

report on bugs.freedesktop.org against DRI -> DRM/Intel
Aug 29 19:04:24 scapa kernel: [ 33.831281] [drm] drm/i915 developers can then
reassign to the right component if it's not a kernel issue.

Unfortunately because of the soft freeze I didn't have a chance to recover
/sys/class/drm/card0/error. But the hang happened pretty soon after boot on my
broadwell CPU, pretty much as soon as I enabled the external screen when logged
on the desktop.
