I'm the maintainer of the FreeBSD PCI code, and that PCI interrupt sharing doesn't work for all cards is (bad) news to me ... Could you please be more specific, and send a VERBOSE boot log (i.e. enter "-v" at the "Boot: " prompt) ? You didn't even give information on the FreeBSD version you are trying to install ... I'll either give further directions (or fix any bug in the code, if there really is one) in order to get you going ... > The current solution is removing the SCSI controller and going with > an IDE disk.
