I reproduced the <a class="bz_bug_link bz_status_RESOLVED bz_closed" title="RESOLVED FIXED - Typo in fonts.conf.in" href="show_bug.cgi?id=4">bug 4</a> times, on 2 occasions no error was emitted before crashing, the 2 other times both umr commands could still run - since the error message looked the same, I'll attach the shorter file, where the crash occurred more quickly. > Also check if adding amdgpu.vm_debug=1 makes the issue reproduce more quickly I used that setting, but it did not seem to make a difference for how quickly the crash occurred - still "some seconds to some minutes".</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
