This really looks strange, as if the drive does not like to
write faster than 4x.

This may be the cause for your problems.
Are you able to repeat this test on a platform with a better SCSI
implementation than Linux (e.g. MS-Win or Solaris)?
The drive usually reports the byte offset that it does not like
but Linux limuts the SCSI request sense data to 16 bytes while
at least 18 bytes are neded in order to find out what the drive
does not like.
It may also be a Linux kernel bug: under some conditions, Linux
seems to modify SCSI commands before sending them to an ATAPI drive.
Your error message may also fit to this problem....
I did see this mayself. I got a
Sense Code: 0x24 Qual 0x00 (invalid field in cdb) Fru 0x0
message from Linux and after rebooting the same HW with Solaris, it
did not show any problem.

The drive seems to do what it announces.

This is a bug fix release that does not get new numbers.
