What's the `pciconf -lv` output for this one? Good point. I had forgotten about the hw.ata.atapi_dma removal and was not even awarethat it had been recently re-enabled. My controller is: atapci0@pci0:17:4:0: class=3D0x010185 card=3D0x82131283 chip=3D0x82131283 rev=3D0x00 hdr=3D0x00 vendor =3D 'Integrated Technology Express (ITE) Inc' device =3D 'IDE Controller (IT8213F)' class =3D mass storage subclass =3D ATA It is used ONLY for the CD/DVD as all other disks use the 3ware RAID contro= ller. Unfortunately, the system is not located where I am, so I can't really try anything until I get over there. Maybe later today I can run into that office and try some of the suggestions. I can certainly build a kernel without ATA_CAM. Thanks! --=20 R. Kevin Oberman, Network Engineer E-mail: kob6558@gmail.com
