In case anyone else hits the same problem I did, I thought I'd post the
answer now that it is solved. Juergens suggestion below removed the boot
time error messages when I loaded the ftape, zftape etc. modules
(incidentally Juergen, the device was definitely /dev/qft1, until I made
your changes , then /dev/qft1 was gone and /dev/qft0 worked for the first
time!).
However I still had the situation where I could write and read to the device
with tar but not cpio. The answer was to set the --block-size option for
cpio to the default block size used by tar ,a value of 20 (* 512 bytes).
This works but I am not sure why, I guess maybe something to do with buffer
sizes.
