	I don't know if combining old driver with new kernel works,
but I have THE SAME config as your's (strange enough :)) and it work
perfectly with 2.2.13 stock kernel compiled with SMP support.
	The base distribution is SuSE 6.2 (which was updated from 6.1)
and I recompiled the SMP kernel myself.

	I've heard 1 problem with the Yamaha CD-RW and the AIC7890 SCSI
chipset which on the P2B-DS(I just realize that yours may not be a dual board?)

	The problem was due to a firmware problem of the CD-RW 4416S.
	If I remember you should have at least version Rev: 1.0g of the CRW4416S.
Look at /proc/scsi/scsi with a kernel you can boot. I will seek my e-mail archive
in ordre to see if it is really the sae problem. 
	DO NOT upgrade firmware without being sure it is the problem.

	Which kernel did you try?
