[Intel-gfx] 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

2016-09-06 Thread linux 

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.
