I've got a 3com 556 miniPCI ethernet card on a laptop, but the generic (or
laptop-) kernel of NetBSD-1.5.1/i386, that provide 'ex0' driver for it is
unable to make it work :

as soon as I try an 'ifconfig ex0 netmask ...', the kernel
replies 'ex0: device timeout' :(

This is strange because I remember to use ex0 for this kind of card on
another laptop (2 months older) without any problem. But perhaps this other
one has not exactly the same 3com chipset (revision changed ?)

does someone have a clue or had the same troubles ?
