I'm not sure what's the effect of this OOPS, kernel seems stable so far
and I can use /sys/class/rfkill/rfkill0/state to disable/enable
bluetooth (it's a desktop computer so no hardware switch).
It wasn't a problem on vmlinuz-3.2.0-20-generic so it seems to be a
regression related to the latest update
