Oh, sorry, I thought that would be obvious from the question.
I'm talking about the bug where the esp gets a reselect after
you have loaded a SCSI command into its FIFO and asked it to
begin selecting a target, after which the FIFO contents are
presented as message data (the SCSI command you loaded) when
you want to see the identify message from the target.
At least, that's my understanding of the bug...
