Did you see an error from the burn program
that would match "Logical block address out
of range" (not by text but by meaning).

I assume this was SCSI error
  5 21 00 LOGICAL BLOCK ADDRESS OUT OF RANGE
So search in the burn program logs for an error
  Sense Key: 0x5 Illegal Request, Segment 0
  Sense Code: 0x21 Qual 0x00 (...) Fru 0x0

We had
  Sense Code: 0x21 Qual 0x02 (invalid address for write) Fru 0x0
but that is not the same error.


[   14.433977] Buffer I/O error on device sr0, logical block 8

I suspect that most of the messages are not
caused by the burn program but by the
hypothetical offender.

None of the burn programs uses an i/o buffer of
the operating system for output. We have our
built-in fifos, and there is the buffer of the
drive. Both should not be on topic for syslog.


> [   14.433974] __ratelimit: 24 callbacks suppressed

I am not familiar with dmesg/syslog details.
Does that mean that 24 SCSI errors were not shown ?
Is that tag [   14.433974] a timestamp ?
How does it translate into seconds ?

The burn programs issue one or two errors and
then abort.

Do you see errors in dmesg if you just put in
a blank CD-R and wait a while ?


Have a nice day :)
