It is always somebody.... but note: nobody is free of errors.

I would carefully check this diff.
1) USCSICMD returns sometimes EINVAL.
This is most likely a bug.
2) None of the SCSI commands from the log did seem to fail.
We did never see any Request sense data, so it may be that this
is the bug in sd.c
Let us check this:
Executing 'Read12' command on Bus 0 Target 0, Lun 0 timeout 60s
CDB: D8 00 00 00 00 00 00 00 00 4B 00 00
/opt/schily/bin/cdda2wav: Invalid argument. Cannot send SCSI cmd via ioctl.
/opt/schily/bin/cdda2wav: Invalid argument. Read12: scsi sendcmd: fatal error
This is a command that most likely failed with a "Invalid command" Sense code
but we did not get a correct reply at all.
This command _may_ fail if the drive does not implement the Sony vendor unique
SCSI command set.
The next problem is that it seems that the command:
Executing 'ReadCD MMC 12' command on Bus 0 Target 0, Lun 0 timeout 60s
CDB: BE 04 00 00 00 00 00 00 4B 10 00 00
/opt/schily/bin/cdda2wav: Invalid argument. Cannot send SCSI cmd via ioctl.
/opt/schily/bin/cdda2wav: Invalid argument. ReadCD MMC 12: scsi sendcmd: fatal
error
CDB: BE 04 00 00 00 00 00 00 4B 10 00 00
cmd finished after 0.000s timeout 60s
fails too. This is a command that cannot fail with an audio CD.
