Comment 10 for bug 221310

Observed in 9.10, also on Packard Bell EasyNote but with Atheros AR5001x.

I have tried both ndiswrapper and madwifi and neither solves the problem. I am new to Ubuntu but will do my best to supply any information required.

dmesg section:
[ 14.554302] ath_pci 0000:00:06.0: enabling device (0000 -> 0002)
[ 14.554315] ath_pci 0000:00:06.0: can't find IRQ for PCI INT A; please try using pci=biosirq
[ 14.554364] wifi%d: request_irq failed
