I'm running into a rather interesting problem here on HEAD with a newer Asus
EEE PC and the "alc" network driver. The device works great when a
cable is plugged in, no issues at all. However, if I unplug the ethernet
and reboot then I get a hard-lock when it tries to bring up the device.
I disabled ifconfig_alc0="DHCP" in rc.conf, and now the system boots
normally, but just for kicks I tried running "dhclient alc0" on it
manually, and sure enough it resulted in another system lockup. (No kern dump,
doesn't even get that far)
Here's some information about the system / device, let me know if there
is any other data / commands I should run and send over.
