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:
