This bug still occurs in saucy when /sys/class/drm/card0/device/power_profile contains "low". I have not seem any lockup with "high" or "mid".
I also tried dynpm in /sys/class/drm/card0/device/power_method and had an immediate lockup that forced me to reboot my computer. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/986524 Title: radeon 0000:02:00.0: GPU lockup CP stall for more than 10000msec To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/986524/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
