The driver loads fine but whenever I bring up an interface, I get "Hardware error, resetting" messages on the screen over and over again, roughly one a second. One user, Claude, reports he upgraded to -STABLE to no avail. I describe the problem in more detail in this thread: http://forums.freebsd.org/showthread.php?t=23297

Hi,

I've committed a fix to -HEAD which should fix the spurious bad
interrupt handling you were seeing.

I'd suggest updating to the latest -HEAD and trying it out.

Please note that power saving stuff in -HEAD for at least the AR5416
and later chips (AR9160, AR9220, AR9280, AR9285, AR2427) is known to
be busted. Please retry without powerd enabled to see if it's actually
a power saving related issue.
