It works fine on catalyst drivers, but fails on OS driver. Without patches from this bug (patch 3&4 or 5) my computer hangs. Signal to monitor is off and monitor suspends, logging through ssh is impossible, system logs are cut before launching X. After applying patch (3&4 or 5) screen goes black, but monitor doesn't go to suspend. I can log in with ssh, after killing Xorg.bin console is visible and operational. Aftr killing X kernel logs show 1868.387061] radeon 0000:01:00.0: ring 0 stalled for more than 395470msec [ 1868.387066] radeon 0000:01:00.0: GPU lockup (waiting for 0x0000000000000005 last fence id 0x0000000000000001 on ring 0) [ 1868.695731] [drm:si_dpm_set_power_state] *ERROR* si_disable_ulv failed Stack trace of running X shows it's waiting for some fence inside radeon dri. I'm attaching dmesg and xorg log after starting and killing X server with patch 5.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
