So you found another Linux kernel bug :-(
*** Linux does not report SCSI timeouts ***
I believe that I did even report this bug more than a year ago.....
But it seems that Linux kernel bugs are not fixed within a resonable
amount of time.
- Please report this bug again.
- I may try to find a way to prevent cdrecord from repeatedly
isuing the command.
Note that due to the kernel bug, this is not possible in general
(libscg already contains too many work arounds for Linux kernel
bugs so it is now impossible to add new ones without breaking
functionality) but it may be in this special case.
