Enumerating only wm works around the panic.
The real problem appears to be the attachment of multiple "pchbN" devices.
They appear to map the same PCI bus multiple times--especially "pchb2".
The wm devices share the same device/function as wm, but on the
spurious "pci3" bus. There is also a spurious attachment of "aac1" and
"ppb1" also on "pci3" at the same device/function as their "aac0" and
"ppb0" counterparts. The "aac1" attach message is "can't find mem space".
Looking at the 'dmesg' output more closely, a more comprehensive workaround
would be to enumerate "pchb0" only.
Probably a BIOS bug (or maybe a hardware bug/quirk).
