I'm 0 for 2 in trying to install FreeBSD from ATAPI CD-ROM
drives. The problem and fix for the first time is in gnats
(kern/6253). This time on another system, it seems that the
drive reports its DRQ type as AT_DRQT_INTR (1), but an interrupt
never occurs before sending the command. Below you'll find
the quick hack I did to make it work and a dmesg.
>From my experience, it seems that ATAPI CD-ROM drives are
very quirky (this is a system at work - no SCSI :() Wouldn't
it make things easier if we had some flags passed down to the
atapi driver, or even had a quirk table for them? I don't
see a correct method of fixing this without flags or quirk
table entries.
BTW, this was 2.2.6-RELEASE.
