Thanks to all for the advice. I knew of the Kernel Debug Kit, my main problem was to be sure that the correct key to press for an NMI was the recessed and not the prominent one (the first hit I found was indeed from someone who was thinking from inside the computer, and was, incorrectly for us outside, defining the NMI as the convex one...).

Unfortunately a hang means that I have too much information and not a nice kernel panic that usually happens near the source of trouble.

If anyone accustomed to kernel dump's showallstacks would like to have a look at it:

http://www.humph.com/tmp/dump.txt

it's about 350KB 6536 lines.

I have sent this same file to ACARD for them to examine.

I'm no Darwin guru, but given the number of threads sleeping in various hfs_vnop_* routines, it's almost definitely disk related. I'd hope ACARD can give you further instructions to debug the hung system state. At least it doesn't look like a vnode deadlock, IMHO.
