A laptop sometimes hangs with GPU reset or might lock completely especially if I leave it turned on in sleep state over night. I'm not sure if it is the same issue because can't read dmesg output, the system doesn't react neither on sysrq nor ctrl-alt-f2, simply a blank screen.
I tried to add "intel_iommu=igfx_off" to kernel options without any luck, the issue still persists.
