I see something similar with Vodafone usb k3520 and connecting the
modem will often give a kernel panic and coredump. I thought I'd
part solved the problem by first booting Ubuntu then NetBSD and I
could then connect the modem and connect via ppp. Last couple of
days this has failed and I've just had panic/core on inserting
usb modem. Ubuntu 'options' driver doesn't so far have a problem
with swapping between pcs. I'm not even sure if panic is from the
cdfs on the stick either rather than the serial connections, plus
some sort of autoupdate when used on XP muddies the water even
further. All three systems I've tried this with have shown same
problem, eee-pc 900, p4-2666 and mini-itx VIA C3. When I
eventually have a good connection there seems to be no further
problem so long as I don't replug the modem.
