Broadcom watchdog timeout with 7.4-PRERELEASE

I've been running 7.X on a Tyan S4881 (4 dual-core Opteron CPUs) since
nearly the beginning of the 7.X cycle, and have just started to see
watchdog timeouts on the Broadcom bge0 GigE port.
This occurs with a kernel and world compiled on 11/22, and also with a
kernel compiled on 11/11 with the 11/22 world.
The errors occur when copying a large number (200-300GB) of files over
a GigE network to a WD USB drive attached to a PC running XP.
There are no Ethernet errors other than those caused by the timeouts.
The system uses an nVidia PCI-Express video board and an LSA 300-8X SATA
card which have not given any problems. I have not been able, however, to
add a SCSI card and I've tried every Adaptec and LSI PCI, PCI-X, and
PCI-Express card available to me. The problem appears to be a mismatch of
the interrupt expected by the card and the interrupt provided by the board.
I haven't found a solution for that problem (yet).
The error is the usual watchdog timeout:
Nov 27 15:34:11 superxeon kernel: bge0: watchdog timeout -- resetting
Nov 27 15:34:11 superxeon kernel: bge0: link DOWN
Nov 27 15:34:11 superxeon kernel: bge0: link state changed to DOWN
Nov 27 15:34:15 superxeon kernel: bge0: link state changed to UP
I intend to switch over to an Intel Pro1000 card since I saw the same
problem some timea ago on another box and switching GigE hardware solved
