Sysrq doesn't work, Numlock goes out, etc. etc. You could look into something a little more powerful for debugging. KDB[1] and kernel crash dumps[2] come to mind. The XFS kernels come with KDB. KDB is a just in time debugger. If the system panics, it will fall into the debugger. If the system locks up, try hitting ^A to break into the debugger. Make sure that it is enabled in /proc/sys/kernel/kdb. LKCD will drop a dump file somewhere which you can then poke through using lcrash. lcrash is a post-mortem debugger, which is also a REALLY good learning tool. Also, a serial console is always helpful when debugging a machine. That way you can capture oopsen easily. [1] http://oss.sgi.com/projects/kdb/ [2] http://sf.net/projects/lkcd/
