Hello,
Just wanted to send a me too on this issue. Whenever it happends I
can see our Cisco switch reporting the interface going down and up as
well (Line Protocol).
FreeBSD localhost.localdomain 6.2-PRERELEASE FreeBSD 6.2-PRERELEASE

(This is a add-in 64bit PCI card.)
I am stress-testing -STABLE on a spare server to aid in making 6.2 as
bugfree as possible.
It is set up as a NFS server with two Linux NFS clients connected
that is concurrently extracting 5 copies of /usr/src to it, and
running a program that creates millions of files with random UID's to
test for QUOTA issues.
On the server I repeatedly dump the exported filesystem with snapshot
and cache enabled. (dump -L -C 32 -af /dev/null ...)
I'm building todays -STABLE on a different server with SMP and two em
NIC's onboard, and will start similar tests on it to see if I can
reproduce the watchdog timeouts there as well.
