Hi,

I am seeing this also on Linux-Next.

/var/log/kern.log:Feb 27 22:52:35 fambox kernel: [   28.202381]
[drm:intel_dp_aux_wait_done] *ERROR* dp aux hw did not signal timeout
(has irq: 1)!
/var/log/kern.log:Feb 27 22:52:35 fambox kernel: [   28.210588]
[drm:intel_dp_aux_wait_done] *ERROR* dp aux hw did not signal timeout
(has irq: 1)!

/var/log/kern.log.1:Feb 22 07:36:04 fambox kernel: [   27.408280]
[drm:intel_dp_aux_wait_done] *ERROR* dp aux hw did not signal timeout
(has irq: 1)!

This seems to be hard reproducible...
Laptop-LCD... Sandybridge Mobile-GT2.

Is there a way to force the error?

Possible patch see [1].
