2.4.5: 'mount /cdrom' doesn't work

2.4.5: 'mount /cdrom' doesn't work

[Harald Dunkel]

Hi folks,

With 2.4.5 my CD and DVD drives have become unaccessable.

Can you reproduce this problem?

Any kernel messages? And please show what happens.

Currently I am back to 2.4.4, but AFAIR I got a message 'no medium found' 
or something like that on the command line.

I have found this in kern.log:

Using 2.4.4 the same CD works in the same drive.

The only changes that could matter would be SCSI driver changes. You
wouldn't happen to use the new aic7xxx driver?

I had the same problem with the IDE CD writer (using SCSI emulation).
