spurious "No medium found" messages with ide-scsi on 2.4.19-pre[45]

[Keith Duthie]

For some reason with my cd-rw, I'm getting spurious "CDROMPLAYMSF: No
medium found" messages when trying to play cds while using ide-scsi
emulation. With the ide-cd module used instead, it works fine. I haven't
tested this with any kernel versions other than 2.4.19-pre[45] (I only
recently got the cd-rw).

I got the following output when playing around with workbone:
play(150,127199)        stopped #1
msf = 0:2:0 28:15:74
CDROMPLAYMSF: No medium found
play(150,127199)        stopped #1
msf = 0:2:0 28:15:74
CDROMPLAYMSF: No medium found
play(150,127199)        stopped #1
msf = 0:2:0 28:15:74
CDROMPLAYMSF: No medium found
                        playing #1   00:03  00:05

The cd-rw is reported on module loading as follows:

Just in case it's important, my motherboard is an abit bx6r2, which uses
the intel 440BX chipset. The ide chipset is listed in lspci as the
82371AB PIIX4 IDE.
