	MATSHITA, CD-ROM CR-506, 8S05	(macppc)

>Description:
Trying to play audio cdroms on any of my big-endian systems equipped with
CD-ROM drives fails but it works on all little-endian systems
(i386,acorn32). Given that I guestimate this is an endianess problem.

Here is what happens on the sparc with esp and the toschiba drive:

cdplay> info

  170  50:13.40         -  225865       -      -
[same output as on working systems]
cdplay> play
cdplay: ioctl(CDIOCPLAYTRACKS): Invalid argument
cdplay> play 1:11 2:22
cdplay: ioctl(CDIOREADTOCENTRYS): Invalid argument
cdplay> volume 100 100
cdplay: ioctl(CDIOCSETVOL): Invalid argument

And the kernel says
cd0(esp0:0:6:0): illegal request, data = 00 00 00 00 26 00 00 8c 00 00
to all three requests
(the kernel is obviously compiled without SCSIVERBOSE)

On the prep (some noname labeld IBM drive connected to siop hostadapter)
results are identical except that the kernel logs this for every request:

cd0(siop0:0:3:0):  Check Condition on CDB: 0x15 10 00 00 1c 00
    SENSE KEY:  Illegal Request
     ASC/ASCQ:  Invalid Field In Parameter List

And on the macppc (matshita drive connected to mesh) I get "Device busy"
instead of "Invalid argument" and the kernel doesn't log anything.
