For info, sometimes ago, I also add a problem with spurious
"[drm:drm_edid_block_valid] *ERROR* EDID checksum is invalid ..."
Sorry, I do not remember from which exact kernel version it was. The
problems occurs for a second screen on DVI output of a laptop. It was
intermittent (ie most of the time, the EDID was correct but sometimes
the EDID was read incorrectly and the output was disabled).
  I "solved" this by adding
options drm_kms_helper poll=N
Using this also ameliorate the stability of my suspend to disk. I did not
try to remove this setup recently ("do not touch a working system!").
My graphic card is an Intel:
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c)
