To trigger you again, I just updated my Pentium M Notebook to 2.3.x svn 
revision 2264, recompiled everything and gave it a try. (kernel 2.6.20)
Some runs of my already well-known software and the machine freezes
during shutdown. No oops, no backtrace, no error message. It doesn't
matter if priority coupling is enabled or not, when it tells me 
'Stopping K Display Manager: kdm' the cursor freezes, that's it. My 
colleague report's the same beahviour on his AMD SMP mashine. The 
Celeron M crashes during reboot showing ugly backtraces like before.
