I get the exact same symptoms when booting with an audio cd in the
drive. I haven't done too much about it as I rarely stuff such things in
my box, but the cd/dvd part of fbsd7 still appears somewhat flakey. I
see the "INQUIRY ILLEGAL REQUEST" below on several boxes. On this
particular machine "atapicd" is commented out in its i386-based custom
kernel config, but it makes no difference as far as this warning/error
is concerned.
