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)!

This seems to be hard reproducible... Laptop-LCD... Sandybridge Mobile-GT2.
Is there a way to force the error?
Possible patch see [1].

That was:
if (!done) {status = I915_READ_NOTRACE(ch_ctl);DRM_ERROR("dp aux hw did not signal timeout (has irq:%i), status=%08x!\n",
has_aux_irq, status);}You applied
if (!done) {status = I915_READ_NOTRACE(ch_ctl);DRM_ERROR("dp aux hw did not signal timeout (has irq:%i), status=%08x!\n",
has_aux_irq, status);{That second '{' is the source of the compile error.
Schei**e, OK I try with a v2.
A hint how to force the error?
