Description of problem:
New Sony PCG-K15 laptop has LAN-Express AS IEEE 802.11G MiniPCI
wireless adapter.  Also known as Atheros/Ambit AR5212 802.11abg
MiniPCI card.  Loading MadWFI ath_pci.o modules gives the following
kernel error:

ath_hal: 0.9.8.6
wlan: 0.7.3.1 BETA
ath_pci: 0.8.5.4 BETA
PCI: No IRQ known for interrupt pin A of device 00:09.0. Please try
using pci=biosirq.
ath%d: request_irq failed

Setting pci-biosirq at boot does not help.

Bug reported to MadWFI users mailing list.  No response yet.

Comment 1 Tom Hutchison 2004-03-20 16:03:34 UTC
After more research etc.  I added " acpi=on " to the kernel boot
options in grub.conf.  ath_pci.o now loads with:

--------------------------------------------
ath_hal: 0.9.8.6
wlan: 0.7.3.1 BETA
ath_pci: 0.8.5.4 BETA
divert: allocating divert_blk for ath0
ath0: mac 5.9 phy 4.3 5ghz radio 4.6
ath0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
ath0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps
24Mbps 36Mbps 48Mbps 54Mbps
ath0: 802.11 address: 00:0e:9b:01:54:03
ath0: Atheros 5212: mem=0x1c010000, irq=11
---------------------------------------------

Not sure why "acpi=on" is necessary, but it fixes the IRQ Not known
problem.

For some reason your system has ACPI but not $PIR (old style) data for
some of the interrupt lines.
