I've attached full dmesg from "drm.debug=0x1e log_buf_len=4M". Will reproduce with drm-tip as soon as I get to that in the next days, but maybe the log from a recent kernel already helps to categorize the issue.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
