To help stop this until Nokia fixes it, I made a little script that checks to see if the process, a kernel level driver process in this case, is eating a lot of CPU. It only does this every 30 seconds or so, and is rather non-invasive. If it detects activity, it watches it a little closer, and issues warnings via espeak if things are going bad, then reboots. I did this just in case you're actively using it (on a call, etc). After a few warnings, it reboots the device, to prevent the system from draining the battery.
