Hi Daniel,
I had already reported this issue in a email-thread called
"[v4.6-10530-g28165ec7a99b] i915: *ERROR* "CPU pipe/PCH transcoder" A
FIFO underrun".
This is still happening here on Sandybridge (and Ivybridge GPU
reported by Chris Bainbridge).
I have updated the bug-report in [1].
Chris B. reports in the BR:
"Bisect result:

commit ed4a6a7ca853253f9b86f3005d76345482a71283

drm/i915: Add two-stage ILK-style watermark programming (v11)"
Any news on that issue?
