Hello,

Can anybody through some light on the following errors which appear on
several XP1000 500au (EV6) running Tru64-UNIX (unpatched). DECevent (V2.9)
does not report any error (or even recognises EV6!) I have subsequently
applied patch kit #1 in an attempt to resolve the problem.

/var/adm # dia -i machine_checks -o full
