I'm happy with that. I have been unable to get a backtrace such as Stanislav commented in #46 because my issue does not generate any backtraces in the logs and I have yet to try to debug it manually. My issue is likely different from any issue resolved by <a href="https://patchwork.freedesktop.org/patch/261135/">https://patchwork.freedesktop.org/patch/261135/</a> given the results are the same after confirming the patch in the kernel.</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> </ul> </body> </html>
