I'm not sure. Debugging a multi threaded application is already tricky 
at best and sometimes nearly impossible, debugging an OS kernel is 
probably even worse. But maybe gdb could produce a backtrace of a crash?

Using debug printk's is also an option, but you need to rebuild every 
time you add, remove or change one (rather time consuming) and they will 
scroll off the screen pretty fast (which is why I was looking for a way 
to write them to a logfile).
