5.2 p2 won't recognize my cdrw drive

Hi

I have been happily running 5.2 Release and had to reboot after security
notification 04:02. I recompiled the kernel and now the new kernel won't
go past my cdrw drive (a primary slave). The message is (printed twice):

ata0-slave : TIMEOUT-SETFEATURES SET TRANSFERMODE retrying (0 retries left)

I then tried a buildworld. That too did not help. I then tried
connecting to secondary channel, it became ata-slave. Same message. So
now I'm back running 5.2 Release. 

Obviously 5.2p2 boots if I disconnect the flat cable and power supply
for the cdrw drive.
