CD-RW not recognized at boot

Dear list;

Upgrading from 5.4 to 6.0BETA1 , I get the following on boot. The kernel 
is not recognizing my CD-RW.

ad0: 19077MB <FUJITSU MHS2020AT E 8307> at ata0-master UDMA33
unknown: timeout waiting for read DRQunknown: timeout waiting for read 
DRQATA PseudoRAID loaded

Comparable boot msg from 5.4 is;

ad0: 19077MB <FUJITSU MHS2020AT E/8307> [38760/16/63] at ata0-master UDMA33
acd0: DVDROM <LG DVD-ROM DRN-8080B/1.09> at ata1-master PIO4

The machine is a Dell latitude C600. I also have a  DVD which *is*  
recognized.  Is support for this particular CD-RW lost in the mists of 
time, or is there something I can check for? /boot/device.hints has the 
correct hints for this drive when compared to the 5.4 hints. Dmesg attached.

Any assistance appreciated.

Patrick Bowen
