problems with scsi cdrom

[matt boex]

howdy all,

i recently installed an adaptec scsi controller, and a
yamaha cd-rw on my rh5.2 box.  i was putting on a
fresh install, all was found by the install program. 
i installed and ran xcdroast and was able to burn a cd
no problem.  well, couple of days later, i tried to
open the cd and it would not open.  i used the eject
command it it worked.  when i try to burn a cd now i
get this error in /var/log/messages.

--------------------

now, i can mount the cd no problem, and view contents.
 also, i am receiving a weird termination error in my
dmesg that may be related.  any ideas?  i am stumped.

here is part of my dmesg regarding scsi and cdrom.
