	I don't know about your CD-R to be broken or not but
I have quite the same CD-RW (Rev: 1.0g):

Host: scsi0 Channel: 00 Id: 04 Lun: 00
  Vendor: YAMAHA   Model: CRW4416S         Rev: 1.0g
  Type:   CD-ROM                           ANSI SCSI revision: 02

attached to the narrow scsi bus of the onboard aic7890 of my p2b-ds and
it does not cause any trouble. 
I run Linux 2.2.10 + aic7xxx-5.1.18-2.2.10.patch.

	At home I have the same Yamaha CD-RW attached to an adaptec 2910 
which does not have any problem either. 

	I have had once a problem with my CD-RW when I wrongly put a 
jumper for enabling the block size of 512k, but I think you didn't change
it when you upgrade the kernel?
