Bug scrub: Reassigned to submitter Lei, do you still reproduce it? Lei can't do the verification. Assigned to me. Created attachment 117809 [details] [review] DP sink power down test It seems that we are failing to disable sink power before we hit the fifo error. Could you give it a go for this patch if this would be helpful. Created attachment 117810 [details] [review] DP sink power down test Oops. Let's fix some compiler warnings..
