https://bugzilla.kernel.org/show_bug.cgi?id=60523 Bug ID: 60523 Summary: Lockup with radeon DPM on Radeon HD5770 (Juniper) Product: Drivers Version: 2.5 Kernel Version: 3.10-drm-next-3.11 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: tdroste@xxxxxx Regression: No Created attachment 106814 --> https://bugzilla.kernel.org/attachment.cgi?id=106814&action=edit dmesg | grep -iE "drm|radeon|power|uvd" after starting a video with mplayer I have some not always reproducible lockup with the latest DPM code. There are 2 scenarios: 1. PC boots, DPM is active and reports different power states and levels in dmesg, but does not change the power level (it's always at power level 2) 2. mplayer is started and plays a video with UVD. DPM switches the power state to UVD and switches between powerlevel 0 and 2 while playing the video 3. When closing mplayer there are 2 possible outcomes: a) DPM switches the power state back to performance and stays in power level 0 or 1. This will stay until something triggers it to switch to power level 2 again. As soon as it's in power level 2 again it's never changing back. b) PC locks up, display is black and VT switch doesn't work until I SysRq+REISUB to reboot the machine Scenario b is harder to trigger but it happened at least 2 times today. dmesg | grep -iE "drm|radeon|power|uvd" -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
