           Summary: PCI interrupts being set as edge, not level
    Kernel Version: 2.6.10
            Status: NEW
          Severity: normal
             Owner: acpi_config-interrupts at kernel-bugs.osdl.org
         Submitter: mjg59-kernel at srcf.ucam.org


Distribution: Ubuntu 4.10
Hardware Environment: Microstart MS6390

Steps to reproduce:

Booting kernel 2.6 gives the following in /proc/interrupts:

           CPU0       
  0:      54678    IO-APIC-edge  timer
  1:         99    IO-APIC-edge  i8042
  5:          0    IO-APIC-edge  eth0, YMFPCI
  8:          1    IO-APIC-edge  rtc
  9:          0    IO-APIC-edge  ohci_hcd, uhci_hcd, uhci_hcd
 11:          0   IO-APIC-level  acpi, ohci1394, ohci_hcd, ehci_hcd
 12:         78    IO-APIC-edge  i8042
 14:       2959    IO-APIC-edge  ide0
 15:         25    IO-APIC-edge  ide1
NMI:          0 
LOC:      54628 
ERR:          0
MIS:          0

Note the lack of interrupts on interrupts 5 and 9. The sound card, network card
and USB fail to work. These are PCI interrupts, but are set to IO-APIC-edge.
Booting with pci=noacpi results in things working. I'll attach the dmesgs for
the two cases (from 2.6.8.1, but the same thing happens with 2.6.10)
