A fix for AR9220 (or generally any PCI card with AR92xx chipset that is not capable of working in the 5 GHz band) was committed to wireless-testing two days ago. > I just booted from a 32bit Ubuntu 9.10 CD; then it works and doesn't > freeze.

Well, it may be a different problem, as the initialization was wrong on 32-bit kernels too. But I cannot be sure that incorrect initialization would prevent the card from working every time. Anyway, it should be possible to try the fix by using the current compat-wireless: http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2.6.tar.bz2 -- Regards, Pavel Roskin
