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.
