John, it seems that possibly your recent changes for PCI bridges could have broken something for my old 440BX/PIIX4/PIII type test machine. Looks like now some I/O resources get assigned to a PCI bridge instead of ACPI. Some highlights follow: ... acpi_timer0: couldn't allocate resource (port 0x4008) ... pcib0: <ACPI Host-PCI bridge> port 0xcf8-0xcff,0x4000-0x4041,0x5000-0x500f on acpi0 ... device_attach: acpi_throttle0 attach returned 6 More data here: http://people.freebsd.org/~avg/ms6163/ I see that _CRS of the Host-PCI bridge indeed claims that 0x4000 range, so I realize that this is a BIOS bug, but I think that perhaps we could have some quirk there to leave this range to ACPI. -- Andriy Gapon
