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). -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/
