* PROBLEM: PX-116A and SCSI emulation in 2.4.21 and 2.4.22 (The scsi wants to send us more data than expected - discarding data)

Good day,
I just installed a Plextor PX-116A DVD-ROM on my Linux system (trying
both kernel versions 2.4.21 and 2.4.22) and I am experiencing problems
trying to set up scsi emulation for it.
The mobo's chipset is a VIA Apollo pro 133A (Southbridge: vt82c596b)
The Plextor PX-116A when running as ide-scsi with **DMA on** cannot
mount disks (cds or dvds), cannot play dvd-movies and cannot readcd a
data-cd.
When I disable the DMA, everything works ok.
When I set it up as ide-cd, everything works ok no matter if the DMA is
on or off.
The drive is currently running at UDMA2 mode (ATA33).
I replaced my old Delta 52X CD-ROM drive with this Plextor DVD-ROM
drive. The old Delta CD-ROM had no problem as ide-scsi with DMA on.
(I want to say in other words that I wouldn't expect this to be a
hardware problem).
I've pasted below the command output and kernel messages from the
following commands:
cdrecord -scanbus
mount
readcd
mplayer -dvd 1
Then, I'll paste output from:
ver_linux
/proc/cpuinfo
/proc/modules
/proc/ioports
/proc/iomem
lspci -vvv
/proc/scsi/scsi
cdrecord -scanbus doesn't produce any weird kernel messages. All the
other commands produce something like this:
ide-scsi: The scsi wants to send us more data than expected - discarding
data
ide-scsi: [[ 28 0 0 0 0 0 0 0 2 0 0 0 ]
]
One last thing: I don't know if it's helpful, but I've read in the
cdfreaks.com forums that internally this Plextor DVD-ROM drive is
actually a Pioneer 120 DVD-ROM. Though, I cannot confirm this piece of
information.
Any kind of enlightment on this matter or help would be welcome :)
TIA

=============
Oh, when running readcd, it just halts on sector 256 and waits there
until I hit Ctr-C and let the scsi command timeout. Sector 256 is not a
standard. Running the command again may make the drive stop reading at
some other sector (i.e 1152).
