The 'error mapping mbuf' error seems to have been fixed by the latest
set of changes to if_bce.c - after upgrading to the latest stable, that
problem stopped happening.
However, instead of that, under rather higher load, we now get the
watchdog timer error instead. This is not good :) I can get it within
minutes with something like building something big from ports, during
the initial source download.

I think moving to stable will fix the mbuf error for you, as that's what
others report. You, and all the other reports I've seen have been
running amd64, which I haven't been (I didn't build the box originally).
I'll know tommorow if amd64 makes much of a difference or not.
Oh, other info - I'm running the standard SMP kernel config with no
modifications.
Sam.
