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
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
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.
