Followup: This also affected Chromium; which was not just updated and worked before. After a reboot, the given page works again in Chromium.
So the Backtrace may be triggered by a separate cause: > [ 7207.128086] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer > elapsed... GPU hung > [ 7207.130257] [drm:i915_do_wait_request] *ERROR* i915_do_wait_request > returns -5 (awaiting 493659 at 493656) > such as an earlier GPU hang. Maybe disabling acceleration after a GPU hang is not working right in the intel driver, though. Chrome is known to use graphics acceleration, and maybe there is a "dri disabled" check missing somewhere. Regards, Erich
