If these are the same patches that CSC got from Ultrix engineering when
I report LAT problems with 3.1, one of them is very bogus.  If you do
the following in adb:

bucket+20<$mbuf

You will probably find the this free mbuf chain is corrupted and/or contains
duplicated entries or loops back on itself.  Very ugly...

Make a big stink and see if you can actually get DEC to fix the problem.
You will have to generate and SPR and push thru your local service
organization that this problem results in system crashes and there is
no work around, etc...

I was making progress on these problems until DEC and I reached an impasse
over a red herring over a 785 memory controller not up to current ECO status,
and I haven't had the time lately to be sufficiently nasty to get more action
out of them...
