I now have all of the relevant SCSI code built into my 1.99.10 kernel (and have had for the past few releases) but still get a hung system whenever I try to tar from a SCSI disk to a SCSI tape (Exabyte).
I have had extremely good help from the local Exabyte support people so I am sure that that side is set up correctly and equally confident that my Adaptec 1542C and IBM DPES-31080 are also correctly configured.
This setup used to work with 1.2.13 but now fails consistently.
My kernel and apps are all ELF built with GCC 2.7.2 and what I thought was 5.3.12 but on checking see is 5.3.9 libc.
I am only guessing, but Alan's suggestion of timing/interrupt problems sounds good to me.
