I let this run for ~30 minutes and did normal work during this time, but was 
not able to reproduce the crash. Our machines seem to have somewhat different 
timings...

Nevertheless, termination of the startup procedure could be done more 
carefully, which I checked in as r987. Another problem might be the sysfs 
files, which are removed before the startup procedure is terminated, i.e., in 
rare occasions those files could be created after the attempt to delete them. 
Since the sysfs files will be removed from the driver in the future, I don't 
want to spend too much time on them right now. You could try to move the timer 
and workqueue related lines in [pod|variax]_destruct into the corresponding 
*_disconnect function (before the device_remove_file lines) to see if it makes 
a difference (though I don't think so).

Do you get any information on the crash (maybe in the system log file, or on 
the console when doing insmod/rmmod on a text console)?
