I purchased a NetGear WPN511 cardbus wireless adapter (atheros chipset)
yesterday.  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?
