Constant watchdog timeouts on em0 with today's -CURRENT

[Joe Marcus Clarke]

I just synced with today's -CURRENT, and rendered by port build machine
useless.  With minimal network traffic (just logging in via SSH with a
TCP NFS-mounted home) I get an immediate watchdog timeout on em0, and
they just keep coming as I type in the session.  The machine is
otherwise idle while this is occurring.

I am currently running:

FreeBSD fugu.marcuscom.com 7.0-CURRENT FreeBSD 7.0-CURRENT #83: Thu Nov
23 01:51:05 EST 2006
root at fugu.marcuscom.com:/space2/obj/usr/src/sys/FUGU  i386

I was running:

FreeBSD 7.0-CURRENT #80: Fri Nov 10 15:53:48 EST 2006
    marcus at fugu.marcuscom.com:/space2/obj/usr/src/sys/FUGU

Which provided stable networking.  Here are my verbose dmesg and kernel
config.  Note: this machine has both am if_em and an mpt card.  Could
the recent MSI changes have exacerbated the em watchdog problem?  What
can I do (besides downgrade) to resolve this?  Thanks.
