Warner,

I am not sure how relevant this is, but I also have experienced
difficulty in shutting down or rebooting with a pccard modem in the
laptop; however, the behaviour has not been consistent.  That is to
say, that though for a particular build of current, the machine will
either reboot cleanly or hang at "uptime" (consistently if I don't
change the OS version), but rebuilding the system may cause the
behaviour to switch.

I have not been following the commit logs too closely, but I haven't
noticed anything that (to my poor eyes) would obviously cause such a
change, for any of the switches in behaviour.  I am not sure, but I
think that the fluctuating behaviour has been present for around a
year.

For reference, the pccard is:
sio4: <IBM 56K Data-Fax Modem> at port 0x3f8-0x3ff irq 11 function 0 config 32 o
n pccard0
sio4: type 16550A
sio4: [GIANT-LOCKED]
sio4: unable to activate interrupt in fast mode - using normal mode


I am the only user of this laptop, so it is available for tetsting
when I'm not thrashing the CPU for work.
