Libata in 2.6.18-rc4-mm1 doesn't recognize my DVD-ROM drive, which is an ATAPI TORiSAN DVD-ROM DRD-N216.
If I add "TORiSAN DVD-ROM DRD-N216" to ata_dma_blacklist[] on line 2990 of drivers/ata/libata-core.c, I am able to mount CDs. However, md5sum fails for some files on the CD, and eventually the drive freezes with the following message. The CD is definitely good since md5sum works on my other computer. If having ssh access to the affected computer would help someone solve this error, I'd be happy to arrange that.
