The card uses irq 10, as does the firewire port and ethernet port (fxp0) on my Dell Inspiron 8100. The laptop is running FreeBSD 7.2 Release (generic kernel). When I bootup the laptop with the wireless adapter in the cardbus slot, I see messages regarding "interrupt storm detected throttling interrupt source". This did not occur prior to adding the wireless adapter. If I insert the wireless adapter after bootup, I don't see the messages on the console or as dmesg output. Otherwise, the adapter works fine. Are interrupt storms a problem? Do I need to worry about them? If so, is there anything I can do about them? Thanks, Andrew
