I seem to have a problem with a parallel port Iomega ZIP drive and
2.4.20. I have seen this on three different machines where the driver
used to work just fine.
This is what I see with kernel 2.4.20-18.8 on one machine.
scsi : 1 host left.

On the same machine with kernel 2.4.18-27.8.0:

I see similar failures on two other machines, one with kernels
2.4.20-18.8 and 2.4.20-13.8, and the other with 2.4.20-18.8.
All of these machines have run the ZIP drive successfully with older
kernels.
To answer two of the obvious questions, I made sure there was media in
the drive and that both the media and drive worked under an older
kernel.
I inserted the PPA module via modprobe. In the case above, a parallel
printer was attached and properly set up. I arranged for the PPA
driver to be installed both before and after the printer daemon
started up. On the other two computers, there was no printer attached.
