Subject: Linux 4.8-rc?: WARNING: at drivers/gpu/drm/i915/intel_pm.c:7866 sandybridge_pcode_write Missing switch case (16) in gen6_check_mailbox_status
Date: Tue, 06 Sep 2016 09:49:52 +0200 [thread overview]
Message-ID: <a6921c29362d397a9fa5315c40cf61a7@eikelenboom.it> (raw)
L.S.,
Since one of the last 4.8 RC's i'm getting the warning below when
booting on my sandybridge based thinkpad.
From what it seems the machine still works fine though.
