SysRQ keys worked, but I couldn't type in X or on the console. I've not been able to reproduce it so far. After rebooting, I extracted the following from syslog: [ 4.513996] usual_tables: module license 'unspecified' taints kernel.

It doesn't look like a normal OOPS or BUG, and it doesn't even seem to have a proper backtrace. Thanks! Alan
