Re: Recent 2.6 kernels can't read an entire ATAPI CD or DVD

[Edward Angelo Dayao <edward.dayao@gmail.com>]

yeah i get this kind of error in my logs as well from my liteon
dvd-rom at home. thats like 6 months old and happened on fc2 when i
had that installed on it. haven't noticed anything on mandrake 10 (the
current distro i use at home) with 2.6.7.

i got the same error on my old notebook, a compaq presario... that was
prior to the drive being sent to that big junk yard in the sky.  i
forget what model that was.  but i was running then...  rh9.

hope this bit helps guys resolve this.
