This is a _trivial_ bug in SCSI Core (error handler, ...) which I hope
will be fixed in the near future (Mike or Patrick will send a patch).
That is, as per my other email, two successive commands (CDBs) should
never be sent with duplicate cmdsn's.
What we're talking about here is a _consistent_ path of a command
through SCSI Core, before it reaches a LLDD. This is currently NOT
the case, thus the duplicate cmdsn...
