Nope...the whole system just becomes non-responsive.  I don't see any
kernel panics/oops displayed.

This is where it gets interesting....remember how I said the last
thing I was this:

10:23:02.167 [I] linux/osspec.c:785: handling /sys/class/net/eth0 net

my laptop has two NICs, eth0: a built-in Broadcom 10/100 port nic.
and eth1, the Intel 2200BG wireless nic.  normally i boot with both
disabled, and i dhclient eth1 after bootup.  since you suggested
ssh'ing in, i turned on eth0 and plugged in a cable and got an IP addr
via dhcp.  running HAL works now.... it won't crash the system
anymore.  so it looks like HAL doesn't like to work when eth0 is down.
unfortunately, this means i can't get you a log since eth0 is down at
the moment.  (i can't ssh in via the wireless NIC right now due to our
network routing in our office... i can get it tonight when i go home
though)

anyway. very interesting. i can workaround this i guess by bringing
eth0 up at boot time before HAL starts, and then bringing it down
afterwards in rc.local or something - but a better solution should be
found.

is there a way to tell HAL to not probe/handle eth0?
