(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. Stephan
