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. Adrian
