1. Can't mount cdrom, connected on Adaptec 1542CF with Kernel 2.4.(3-5)

2. Description
On Kernel 2.2.(3-5) with aha1542 as second SCSI-Controller
mount -t iso9660 -o ro /dev/scd1 /cdrom gives the following Message:

mount: wrong fs type, bad option, bad superblock on /dev/sdc1
or too many mounted file systems

But I can burn CDROM and read Images from CDROM,
mean copy Iso9660- and Audio-CDs are ok.

When I switch back to Kernel 2.2.19 there is no Mount-Problem.
There is no mount Problem with aic7xxx, too.

7.7 Other notes
There are 2 SCSI-Controller running on the System:

the first: aic7xxx (Adaptec 2940UW)
Note: The cdrom on aic7xxx can be mounted, without any problem

the second: aha1542 (Adaptec 1542CF)
Note: No cdrom can be mounted, but I can read Cdrom-Images with cdrecord.
Tapes and Scanner running fine
