I'm having watchdod timeout problems with the bge driver in 7.4-PRERELEASE
on a Tyan S4881 motherboard (the S4881 has 4 Opteron sockets, 2 PCI-E
slots, and 3 PCI-X slots, plus VGA and dual Broadcom "bge" GigE ports.)
I don't know if this problem also affects the similar Tyan S4882 motherboard,
which appears to be much more common. I have a S4882 and can swap it for
the S4881 and test this, if anyone is interested (there are a lot things
to unplug and unscrew, so I'd rather not if there's no reason for it).
I've been able to isolate the problem to the following patches

Reverting if_bge.c, if_bgerec.h, brgphy.c, and brgphyreg.h to the version
that existed on 10/7/2010 allows me to do a 7.4-PRERELEASE buildworld/
buildkernel/installkernel cycle and the resulting kernel does not exhibit
the watchdog timeout problem.
The problem appears only on samba shares exported to a Windows XP Pro client
(I've been copying a directory with 17GB of "Ghost" images as a test).
The dmesg for a kernel that failed (containing the patches above) is as
follows:
