Comment 16 for bug 414560

+1 me too - but on an HP dv6 series laptop with an AR9285.

lspci -v output:

Kernel I'm running is:

built from on Jaunty.

I've also posted the issues on ath9k-devel mailing list, but not gotten any helpful replies from there.. :(

Maybe, I'll give wireless-testing a try.
