I recently tried running an SMP kernel here, even though my box is UP,
as a temporary workaround for the broken state of UP kernel builds on
amd64.  When I did, I experienced the fxp timeouts.  When I finally got
a UP kernel to build again, the fxp problem went away.

Perhaps there's a clue there.  :-)
