Hi,

I just got hold of a JavaStation (don't know which precise model, see
dmesg below) and it panics because of "crazy interrupts".

Actually, the problem comes from the serial port emitting interrupts
while no handler for it is registered.

Line
com0 at obio0 slot 0 offset 0x3002f8: ns16550a, working fifo
should also show that interrupt 13 (0xd) is assigned to this chip.

I don't know which probe is to blame (in MI com.c, or in obio code?).
Could someone help me debug this?

If I don't attach com* at obio, I can otherwise successfully boot the
machine to multiuser.

thanks in advance,
 Aymeric
