Hello,

Sorry for the delay, I was confused about managing so many patches,
but I realized that you're sending me cumulative patches that I can
apply to the original. I just want to remind you that I still have the
patches to the other two files: libata-eh.c  libata-sff.c

Applied. It did not change anything visibly (dmesg attached). I have
also been getting other SCSI errors since we started communicating
with the device (search for sr0 in dmesg). I wonder if they give any
hints? Here's one:

sr 4:0:0:0: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE
sr 4:0:0:0: [sr0] Sense Key : Aborted Command [current] [descriptor]
Descriptor sense data with sense descriptors (in hex):
        72 0b 00 00 00 00 00 0e 09 0c 00 00 00 02 00 00
        00 20 00 00 a0 40
sr 4:0:0:0: [sr0] Add. Sense: No additional sense information
sr 4:0:0:0: [sr0] CDB: Read(10): 28 00 00 00 00 00 00 00 40 00
end_request: I/O error, dev sr0, sector 0

Thanks,
Cengiz
