There have been several threads related to CD/DVD ROM problems and one pr: i386/37420. Each thread stopped after atacontrol was used to set the drive into dma mode, so I guess this worked for their case. However, since both pio and dma mode give the same error on my CDROM drives I reverted to 4.5-RELEASE-p3 and watch the mailing list to to see if anyone else has the problem and check cvsup to see if sys/dev/ata is modified before I try -stable again on those systems. 4.5-RELEASE-p4 does not have any changes to atapi-cd.c so I would expect that to work (I have not tested this yet). >I have tried reverting to the wd driver and included mcd in the kernel, >but mcd never shows up in dmesg output.

I don't know about this, but I am fairly sure that mcd is only for a Mitsumi ISA interface card. >mcd is for Mitsumi drives which apparently use a non-conforming ATAPI >interface.
