As you assumed, the hardware is exactly the same  as it was with RH9. I
just did a reinstall from scratch because I made so many changes to RH9
that the system was unupgradable.

In my case, I am able to read  single volume tapes but when come the
time to change the tape, that is where it fails. It looks like the end
of tape is not well detected. I will try with aic_7xxx_old tonight to
see if there is any changes. 

If there is issues with scsi drivers, that could be what is my other
problem with my Plextor CD Writer who hangs the system with a scsi reset
when I try to write a CD... But I don't know if it is realy related to
the driver because the same problem appears even with the other SCSI
adaptor I have (ncr53c875).
