Fix on mailing list. It also happens on BYT and BDW. Upgrading to regression. Also this breaks runtime PM nowadays so has serious impact. Ramping up priority. increase priority to high. Should be resovled with latest -nightly. Created attachment 100948 [details]
dmesg
This bug able to reproduce on latest -next-queued(a7bac7fb6c8b077fc11084bf539989f43a45976a) and -fixes(ce9557b9fe17012dea2447e643a1047c27a00838).
(In reply to comment #5) > Should be resovled with latest -nightly. I didn't reproduce this issue on latest -nightly(1d3e80d9ff52ecaeecc5b78de32f9bb07ad2231f). Because I unable to reproduce on latest -nightly, only able to reproduce on -fixes and -next-queued on IVB. Change the status back to Resolved fixed. I will further investigate if this bug is fixed. Checked on latest -fixes and next-queued. This bug had fixed. Closing verified+fixed. |
