<pre>Looking at the logs, this link failure is happening because of the aux timeouts
before the link training. Meaning that the AUX power domain is not on at that
point.
What test case are you running to put trigger S3 state and waking it up from
S3?
Would be interesting to try this with i915.disable_power_well=0 set for the
kernel parameters or manually setting this in i915_params.c and rebuilding the
kernel.
Let me know if that fixes it.
