Hello,
now that i have two machines running FreeBSD-3.1-Stable, i
can see a strange behaviour of the code looking for PCI
devices at boot on one of them. here is dmesg:

Of course on the other one there is probe for PCI bus 0 and 1
only. I wonder what could cause such strange lookup.
I have already answered this same question, but got no
answer, so i waited to see if this problem would survive an
upgrade to recent Stable, which is the case.
Thanks
