            Bug ID: 285007
           Summary: Warning message about decoded bus range in
                    acpi_pcib_acpi_attach doesn't seem to match
                    code/comments
           Product: Base System
           Version: 14.2-RELEASE

There's a check in sys/dev/acpica/acpi_pcib_acpi.c (around line 445) which
expects "If there is a decoded bus range, assume the bus number is the first
value in the range".

I know nothing about ACPI or PCI bridges, so I can't comment if that's
sensible; however, the comment and code don't seem to match the warning message
which is output - 128 is definitely within the range 32-255, which is a bit
confusing. :-)

pcib9: <ACPI Host-PCI bridge> on acpi0
pcib9: WARNING: BIOS configured bus number (128) is not within decoded bus
number range (32 - 255).
pcib9: Using range start (32) as bus number.
