Heyas folks --

So far I've been netbooting my O2, with ~no load between reboots. Now  
that I have the console working, I wanted to add support to XFree86.

Checking out the xsrc tree to the NFS driver eventually caused the  
machine to lock up. Rebooted, and checked it out directly from the  
NFS server. NFS server had no problem, so time to build xsrc over NFS  
-- locked up again. Finally gave up on NFS, so I setup my hard disk,  
netbooted a kernel with root on sd0a.

This is when the real problem started happening -- I can't seem to  
bring the mec interface up. I get a strange semi-hang from doing this:

	o2# ifconfig mec0 up
	o2# ifconfig mec0 inet 192.168.10.20 netmask 255.255.255.0
	<semi-hang>

I call it a semi-hang because the keyboard still emits characters to  
the screen etc, but I can't for example switch virtual consoles,  
enter DDB, or ^C ifconfig.

Any ideas? I've switched to an ex(4) in the meantime, but that's a  
bit of a pain as arc doesn't let me tftp boot with it. dmesg follows:
