Could this be related to a problem we've been seeing on the 860T,
resulting in the following messages?

This only seems to occur when receiving bulk data on a TCP connection -
we never saw it ftp-ing onto a system when we used an NFS filesystem,
but now that we're booting a ramdisk, an FTP get of more than 10-20k
results in a guaranteed transmitter timeout.
