CDROM troubles with fedora beta 2 (0.94)



A 'mount /dev/cdrom /mnt/cdrom' hangs for a long time, then quits with an I/O 
error. The system has a KS57A motherboard and a Aopen CDRW4048. the 
/dev/cdrom entry is soft linked to /dev/scd0 as it should be. Here's the 
output I get:

/dev/cdrom: Input/output error
mount: block device /dev/cdrom is write-protected, mounting read-only
/dev/cdrom: Input/output error
mount: you must specify the filesystem type

Here's the corresponding snippet from /var/log/messages:
