--- Comment #12 from Emanuele <[email protected]> 2011-09-18 14:31:18 PDT --- Hi Alex, now I'm using kernel v3.0.4. I noticed that I have freeze also when I put my current wire into socket, sometimes. Remember that I receive this message on standby or when I do: --- echo "low" > /sys/class/drm/card0/device/power_profile --- NMI: PCI system error (SERR) for reason b1 on CPU 0. Dazed and confused, but trying to continue --- and I do this when the current wire is pulled off whereas I do: --- echo "auto" > /sys/class/drm/card0/device/power_profile --- when is inserted. I have noticed also that sometimes I receive that message at boot time: ---[drm] Initialized drm 1.1.0 20060810 [drm] radeon defaulting to kernel modesetting.
