[   65.891898] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[   65.891900] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[   65.891902] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[   65.891905] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

Comment 4 Damjan Georgievski 2017-09-22 22:23:28 UTC

Happens to me too when booting 4.13.3 (also .2).

Hardware is
Thinkpad T450s, latest bios updated
DMI: LENOVO 20BWS10N00/20BWS10N00, BIOS JBET65WW (1.29 ) 06/15/2017
i7-5600U (Broadwell)

Booting 4.13.3-1-ARCH hangs when starting Xorg (sddm), the message I caught via ssh in the first second before it was hung completely was:
[  123.917760] DMAR: DRHD: handling fault status reg 2
[  123.917765] DMAR: [DMA Write] Request device [00:02.0] fault addr 108a000 [fault reason 23] Unknown


4.12.13-1-ARCH works fine
4.9.51-1-lts works fine too

Distro is Archlinux.
Booting in CLI works fine too.
Booting with "intel_iommu=on,igfx_off" on the kernel command line also works fine.
