I have a fxp network card in an AlphaPC 164LX. The card is unused, I am
using another interface. When I try to reboot the machine by typing
reboot, it panics after syncing discs and goes to the debugger.

When the card isn't in the machine, it reboots OK.

dmesg is included, note this includes the panic message.
(Having dmesg from previous boot is a wonderful feature btw! How is this

And, how to get the backtrace from the core dump? I suppose it will be

Thanks	Pavel Cahyna
