Subject: [BUG] 2.5.8: ACPI: PCI IRQ remapping goes wrong.

Hi guys,

My SCSI card didn't work anymore, my NIC was unable to connect and my SB
Live! didn't work anymore. I thought 2.5.8 was a huge mess :)

Anyway: ACPI sets up IRQ remapping to IRQs > 15, but all PCI devices claim
the old =< 15 IRQ's. My guess is that the ACPI code doesn't update the pci
irq data.

If it matters: The system I talk about is a dual PII 333, on an Intel LX
chipset. 2.5.6 did boot fine.

Jos:

Using IO[S]APIC and ACPI_BOOT is broken in 2.5.8 and the acpi-patches
acpi-20020404 and acpi-20020419. The ACPI SMP booting code is re-worked, and
so this problem should be resolved soon. FYI, acpi-20020419 informs you of
this in a nice kernel panic.
