atheros wifi broken with gutsy update [madwifi]

[dperham]

Binary package hint: linux-restricted-modules-2.6.22-14-generic

The atheros wireless card in my Aspire 3502WLCi worked until a recent set of updates were applied. After that my built in wireless did not work. In dmesg|less I saw the following:

[ 16.012000] ath_hal: module license 'Proprietary' taints kernel.
[ 16.012000] ath_hal: 0.9.18.0 (AR5210, AR5211, AR5212, RF5111, RF5112, RF2413, RF5413)
[ 16.452000] wlan: 0.8.4.2 (0.9.3.2)
[ 16.484000] ath_pci: 0.9.4.5 (0.9.3.2)
[ 16.484000] PCI: Enabling device 0000:00:0b.0 (0010 -> 0012)
[ 16.484000] ACPI: PCI Interrupt 0000:00:0b.0[A] -> GSI 17 (level, low) -> IRQ 22
[ 16.484000] wifi%d: unable to attach hardware: 'Hardware revision not supported' (HAL status 13)

I believe that the madwifi version in the linux-restricted-modules-2.6.22-14-generic version 2.6.22.4-14.10 broke the wireless.

Rolling back the package to version 2.6.22.4-14.9 fixed the problem.

the rolled-back package version 2.6.22.4-14.9 yields the following entries in the dmesg log

I was mistaken. It seems that my wifi sometimes works when I boot, and sometimes it doesn't

Same here, either with Hardy.
BTW, which atheros card are you talking about? Mine is a AR5006EG (or a AR5007, maybe it is badly recognized).
Works (but quite bad, sometimes connection hangs up) with ndiswrapper.

There is a patch on madwifi's site for my wifi card: http://madwifi.org/ticket/1679
I don't know if it is already integrated in Ubuntu.

Cheers.
