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.
