To follow up on my own post of earlier today, I tried the 1.4.2_ALPHA kernel
from ftp.netbsd.org and find that it panics regularly every 30 minutes,
just when innd gets ready to start receiving articles in mass.  Again, I've
notated a backtrace and find that ffs_nodealloccg causes the machine to
throw a memfault_sun4m exception.  I think there's potentially a real
problem here, anyone able to shed light on what it is?
