pcib allocation failure

[deeptech71 at gmail.com]

pcib1: <ACPI PCI-PCI bridge> at device 1.0 on pci0
pcib1: failed to allocate initial prefetch window: 0xd0000000-0xfaffffff

the console output is cut shortly after those 2 lines (but the machine
seems to continue booting, as i have reset'd the machine, after which
"/" was found to be improperly dismounted).

this happens with a the r221862 kernel, but not with the r221309 kernel.
a quick search reveals something:
http://www.freebsd.org/cgi/query-pr.cgi?pr=143874 (i have no idea what
that is).
