And you have an interrupt storm on irq 10?

It depends on what drivers you have enabled.  Do you have usb and cbb
both enabled?  I just got a new laptop where cbb freaked out that also
got an interrupt storm as soon as I inserted a card (or booted with a
card inserted), and the root problem was that cbb was using resources
in use by another PCI device due to our brain-damaged PCI resource allocation
code (or rather, the lack thereof).
