I agree and want to.  I tried, but the AS1200s would hang with
'explift is 0' .. (sic) so I pulled out those disks and put the
1.5 back in .. at the same time swapping out an ex (905) device
for a tlp (DE500) and now both machines repeatedly (like every
20 minutes or so) will panic with this load_mbuf error even 
with the generic kernel.  Is there at least a work around ..
is it the ethernet cards?  .. I don't remember them every giving
that panic before during the past year ..
