Thus we can at least check whether the two forms of GPU hang I'm experiencing (recoverable and non-recoverable) are actually the same error. This one is now from a vanilla 4.11-rc2 without your patches, but I can repeat again on a recent (and patched) drm-tip if that's helpful.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
