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).
