If you have another machine, you can patch 'kernputc' to either 0x2f8 or
0x3f8 and all kernel printf's will go to the serial port (at 9600 baud).
The problem with osm is that it does not catch a panic message, you have to
go look at the dump to find the panic since the 'cat' will never get dispatched
after a panic. If you have another box that can record stuff off the serial
port it is a great way to log disk errors and other stuff that usually scrolls
away.
