I have a Dell 1950 here that's been dedicated to helping solve this
problem.  I can reliably reproduce the watchdog timeout by doing
the following steps:

1) Mount /usr/src via nfs
2) start a -j99 buildworld
3) On a different terminal, do tar czvf /usr/src/temp.tgz /big/directory

Usually only takes a few minutes before a watchdog occurs, and I have
no more networking.

Your patch applied cleanly, and everything built OK.  The results are:
a) My USB keyboard stopped working :(
b) The problem does _not_ improve.

In my case, it's a bce driver that's doing it.  I also have some em
cards in this machine that I can test if the information will be
helpful.

This is quite a show-stopper for us, if there's any other testing/etc
I can do, _please_ let me know.  I might even be able to get remote
console access to this machine approved for a developer.
