Yep, that's exactly what it's doing (but you don't have any ?). This
problem occurs on both the Cumana and Powertec drivers when no devices
are on the bus, with slight differing symptoms.

Well since the product id hasn't changed the kernel still attaches it
using the ptsc driver. I'd be surprised if the card has changed
radically, But since I don't have a version 2 card I can't test
it. Anyone else got it to work ?

Is everything on the bus turned off then ? Try turning on the CDROM
and rebooting.
