--- Comment #3 from Michael Daum <mic.daum at gmx.de> ---
The patch from Ilia prevents the kernel from crashing. Reboot does not fail any
longer. Additionally _most_ of the time both monitors come up at reboot.

But on some reboots one of the monitors stays black and the kernel logs
following error (from dmesg):

[    0.955154] nouveau 0000:01:00.0: disp: outp 04:0006:0384: link training
failed
[    0.973972] nouveau 0000:01:00.0: disp: outp 04:0006:0384: link training
failed
[    0.974279] nouveau 0000:01:00.0: disp: link_nr = 0; dpctrl: 00401101


The value of dpctrl is always the same (00401101) then.
