           Summary: ACPI + PCI are not aware of ISA interrupts in use or
                    required to be in use
    Kernel Version: 2.5.xx-2.5.63bk5
            Status: NEW
          Severity: normal
             Owner: andrew.grover@intel.com
         Submitter: spstarr@sh0n.net

Distribution: LFS
Hardware Environment: IBM 300PL 6892-N2U PIII (Katmai) 450Mhz
Problem Description: ACPI/PCI dont notice ISA irqs used

Steps to reproduce: If I set pci=noacpi I have no IRQ conflicts. However, disabling
pci=noacpi I get conflicts even though all IRQs are correct and are properly
allocated.

the /proc/interrupts for when pci=noacpi is set and disabled are identical however
conflicts are reported by the ISAPnP OSS Soundblaster driver.

PCI routing with ACPI isn't aware of ISA interrupts in use or ISA interrupts required.
