CVS commit: src/sys/arch/x86/x86

[Joerg Sonnenberger <joerg%netbsd.org@localhost>]

Module Name:    src
Committed By:   joerg
Date:           Tue Jun  3 20:34:15 UTC 2008

Modified Files:
        src/sys/arch/x86/x86: mpacpi.c

Log Message:
Make the logic for _BBN overrides less aggressive. When mpacpi_get_bbn
failed and the current goal is to enumerate all PCI bus and this is the
first PCI host bridge, just assume it is bus 0 and ignore the error.
When querying the bus number, assume that the system paniced earlier if
an error happened and this is not the first/only PCI host bridge and
override the BBN as 0 in that case.
