Hi, just yesterday I Attempted to upgrade my server machine to the
lastest -STABLE. Unfourtunately, the kernel kept panicing. I've seen it
panic both in the disk code, and the arp code, although unfortunately
i've only managed to get a decent crash dump out of the former. I
(should have) attatched the resulting crash dumps. 
(unfourtunately the source locations seem a little foobared)
