Me too kind of response. There, I have ath and snd_hda sharing interrupt on the Acer 945GM based laptop. I need to provoke the interrupt storm, though. It starts after I do "ifconfig ath0 up; ifconfig ath0 list scan" without configuring network. Doing "ifconfig ath0 down" stops the storm. Otherwise (i.e., when associating with ap) interface works normally. Releng_6.
