I did the testing with Adaptec 29320LPE. I have also 29160N on a PCI slot, but it does not support MSI. Initially I was trying to use PCI pass-through with IOMMU which requires MSI. I have also seen one kernel crash when probing / initializing 29160N but that was with Xen and IOMMU enabled. Multi Pros have also a Firewire port. These are known issue over time when scanner refuses to initialize if set to use Firewire port but still work with SCSI port. Jarkko
