Hmm... I'm still confused here.  Let me see if I can figure it out.

When HPET is enabled and you try to boot a FreeBSD CD, you receive
the READ_BIG errors over and over, and it never stops.

But if you disable HPET and try to boot a FreeBSD CD, it works.

Once the OS is installed (with HPET disabled), if you run "kldload
atapicd", you receive the following error:

  g_vfs_done(): acd0[READ(offset=32768, length=2048)] error 5

And if you try to mount the CD by doing:

  mount -t cd9660 /dev/acd0 /mnt/cd0

Then you start seeing the READ_BIG errors again, and they never
stop.

Is this correct?
