To chime in with my experience: I recently installed 5.2-RELEASE on an IBM
Thinkpad 600X (2645-4EU).
I could not get PCI interrupts working correctly using ACPI. I ran
out of time to fiddle with it and went back to APM and it is working.
(Well, pccard and cardbus cards are working; suspend still wedges the
I did upgrade to the latest BIOS available from IBM (ITET55WW, 1.11).
The cardbus/pccard problems are because ACPI does not route a usable
interrupt to cbb0/cbb1. In dmesg I get:
pcib0: slot 2 INTA routed to irq 3 via \\_SB_.LNKA
cbb0: <TI1450 PCI-CardBus Bridge> mem 0x50103000-0x501-3fff irq 3 at device 2.0 on pci0
cbb1 also gets irq 3. In W98SE or FreeBSD 4.9 or 5.2 w/ apm, they get
irqs 9 & 11 respectively.
I tried setting a hint, eg (in /boot/device.hints):
but it does not work because the call to
dev/acpica/acpi_pci_link.c:acpi_pci_link_set_irq() dies because its
call to acpi_pci_get_current_irq() dies because its call to
acpi_pci_link_get_irq_resources() fails because NumberOfInterrupts ==
0 (in acpi_pci_link_get_irq_resources()). I assume that this is
related to Greg's finding the the IRQ in the PIR was set to -1???
(Sorry I am ACPI-ignorant.)
That is as far as I got in trying to figure out what is going on. Any
suggestions are welcome. I do not include a full dmesg, but am happy
to provide such or any other information on request.
