Problem with IRQ on W-Lan Atheros 5212 (madwifi)


Got an Sony Notebook (K115Z) with an Atheros 5212 W-Lan-Card.

I installed the 2.6.5 kernel and installed the madwifi modules.

The modules wlan.ko and ath_hal.ko could be loaded without any error but the module ath_pci.ko gives this errormsg:

PCI: No IRQ for interrupt pin A of device 0000:00:09.0.
ath%d: request_irq failed
lspci -s 9 -vv

0000:00:09.0 Ethernet controller: Atheros Comm., Inc. AR5212 80.......etc
Interrupt: pin A routed to IRQ 0
I tried everything:

noapci... and so on.

yesterday the w-lan card worked but after a new kernel-compilation it didn't work again. I dont know if it is the kernel (I tried a lot of parameters and everything that had a little bit to do with pci or apci, but nothing helped)

I hope somebody can give me some tips or got the same problem and solved it.

I searched with google for days, and found a lot but nothing really helped

Ciao, Subby

I'm having a VERY similar issue.

I've already posted my issue here:

Let me know if you have any ideas on how to get this to work.
