In the meantime, I tried --rate to use a 30Hz rate, and that did crash it. The symptom is a bit different that previous kernels though, the internal LCD didn't switch to displaying garbage, but it did hang. I recovered after a few seconds, but then all displays blinked (looked like it re-detected the external monitor) and this time everything hung. There was nothing in the sysfs "error" file after a reboot.</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>
