Created attachment 117723 [details] dmesg-4.1.5 All is fine with version 4.0.5, upgrading to 4.1.5 gives reproducible gpu crash. It crashes immediately as the driver is loaded. I'm attaching the full dmesg output, the relevant part is at the end. I'll also attach /sys/class/drm/card0/error.

Looks like an iommu related issue. Could you please try booting with intel_iommu=igfx_off?
Hi and thanks for replying! I tried that and the errors were completely gone but my external monitor was not detected (properly). Meaning, on the virtual console the resolution for it was very low and when I start X it is not detected at all. I'm attaching dmesg and Xorg.log.0 from both 4.0.5 and 4.1.5. diffing them doesn't reveal any problem (apart from the fact that EDID for output DP2 which is the external monitor doesn't discover anything in 4.1.5's Xorg.log. I'm not sure if this problem is related to this bug at all, if you feel like it's not, please close the bug.

We seem to have neglected the bug a bit, apologies. Aayla Secura, since There were improvements pushed in kernel that will benefit to your system, so please re-test with latest kernel and mark as REOPENED if you can reproduce (and attach fresh gpu error dump & kernel log) and RESOLVED/* if you cannot reproduce.

Timeout. Assuming that this is not occurring anymore. If this issue happens again, re-test with latest kernel and REOPEN if you can reproduce (and attach fresh gpu error dump & kernel log)
Many apologies, the previous post got past me. I tested it today with 4.8.4 and cannot reproduce the crash. Can't say anything about the external monitor issue as I have no access to a monitor at the moment.
