(If it were properly programmed to do so, I suspect it wouldn't get into this state in the first place.)
IIRC (im not awake enough yet) one of the issues with the driver was that with a system reboot the chipset wouldn't properly clear the memory leaving it in a state where it was possible to see this issue without a huge amount of load. That said I haven't rebooted since PR1.3 came out.

Edit: Basically the driver needs fixing...either Nokia or someone else who's worked on it.
