I'll try that My memory is more than a bit flakey, but this did eventually ring a bell.,. And googling I see that I have tried that tip before without success: https://bugs.freedesktop.org/show_bug.cgi?id=101288 If you look at the logs attached to that bug, you'll see that the PC was running with "intel_iommu=igfx_off" at the time of the hang: [ 54047.182] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-4.9.0-3-amd64 root=UUID=71507198-90f4-4c25-be41-efc47d2dedd1 ro intel_iommu=igfx_off I believe the GPU hang reported in that bug is the same?
