If you have a serial port on that machine, then you can enable the
serial console with "console=ttyS0,115200" on the kernel command
line. Use a second machine to record the data.

If you don't have a serial, then you should be able to do something
from the initrd shell. Your ethernet driver should be loaded already,
if not just compile it into the kernel instead into a module. Now you
can get it out over the net from that shell.
 
A third option is to use netconsole. Do this on mainline with the
"threadirqs" option, as I haven't tried netconsole on RT.
See Documentation/networking/netconsole.txt

Good. So it's not RT wreckage :)
