Question: 3.1.8 not finding interrupts 

Forum: PCMCIA Installation and Configuration Issues

I tried upgrading from 3.1.2 to 3.1.8 today (kernel version is 2.2.14). Under 3.1.2, there are no problems: 

Linux PCMCIA Card Services 3.1.2
  kernel build: 2.2.14 #1 Thu Jan 6 10:07:52 EST 2000
  options:  [pci] [cardbus] [apm] [pnp]
PnP: PNP BIOS installation structure at 0xc00fdae0
PnP: PNP BIOS version 1.0, entry at f0000:423d, dseg at f0000
PCI routing table version 1.0 at 0xf5cd0
  00:0a.0 -> irq 10
  00:0a.1 -> irq 10
Intel PCIC probe: 
  Cirrus PD6832 PCI-to-CardBus at bus 0 slot 10, mem 0x68000000, 2 sockets
    host opts [0]: [ring] [0/7/4] [3/17/4] [pci irq 10] [lat 168/176] [bus 32/34]
    host opts [1]: [ring] [0/7/4] [3/17/4] [pci irq 10] [lat 168/176] [bus 35/37]
    ISA irqs (scanned) = 3,4,5,7 PCI status changes
  Cirrus PD6729 PCI-to-PCMCIA at bus 1 slot 10, port 0xecfc, 2 sockets
    host opts [2]: [ring] [1/3/2] [1/9/2]
    host opts [3]: [ring] [1/3/2] [1/9/2]
    ISA irqs (default) = 3,4,5,7,12 polling interval = 1000 ms

but with 3.1.8, it only finds irq 5. the compile options are the same with both versions, as are the PCIC_OPTS, which are just "cs_irq=9". i tried adding "do_scan=0 irq_list=5,7,9,10" to the PCIC_OPTS for 3.1.8, but this didn't cure the problem.

any ideas?

Other devices are using those interrupts

It would be useful to also include the messages for 3.1.8, since that
is the version you're having trouble with.

If you enable PnP BIOS support, then 3.1.8 is going to be more
aggressive about excluding interrupts that are known to be committed
to other devices.  Check /proc/bus/pccard/irq to see what devices are
supposed to be using these interrupts.
