--- Comment #12 from Karl Schendel <schendel at kbcomputer.com> ---
Ok.  Not sure what the latest drm-next is, I found a recent looking
drm-nouveau-next and it did the same thing.

Monitor is blanked (backlight off) via:
[  225.790860] nouveau D[     I2C][0000:05:00.0] AUXCH(3): 8: 0x00000600 1
[  225.790894] nouveau D[     I2C][0000:05:00.0] AUXCH(3): wr 0x00000002
[  225.790897] nouveau D[     I2C][0000:05:00.0] AUXCH(3): wr 0x00000000
[  225.790899] nouveau D[     I2C][0000:05:00.0] AUXCH(3): wr 0x00000000
[  225.790901] nouveau D[     I2C][0000:05:00.0] AUXCH(3): wr 0x00000000
[  225.791037] nouveau D[     I2C][0000:05:00.0] AUXCH(3): 00 0x01108000
0x10000000

and the unsuccessful attempt to restore backlight is:

[  251.285375] nouveau D[     I2C][0000:05:00.0] AUXCH(3): 8: 0x00000600 1

[  251.285391] nouveau D[     I2C][0000:05:00.0] AUXCH(3): wr 0x00000000
[  251.285393] nouveau D[     I2C][0000:05:00.0] AUXCH(3): wr 0x00000000
[  251.285395] nouveau D[     I2C][0000:05:00.0] AUXCH(3): wr 0x00000000
[  251.285529] nouveau D[     I2C][0000:05:00.0] AUXCH(3): 00 0x01108000
0x10000000

Full log attached as it's rather lengthy.  ***NOTE*** lines show when things
