For me it looks unbelievable too.

I've seen a similar problem (timeout on odd transfer count)
on SCO UnixWare and it could be tracked down to a driver bug.
As Frederick only has problems with a SCSI commands that needs an
odd transfer count _and_ the result is the same (timeout) it is
very improbable that there is a different cause.
