scanner/sane/SCSI problem
I am setting up an old Ultra 1 as a scanner machine, and I have had
some problems making sane connect to the SCSI-scanner. I have tried
two different kernels, 2.2.20 and 2.4.17, both compiled with
make-kpkg. It works only with the older kernel.
Below a copy of issued commands is seen. The machine has been rebooted
but except from the differences in kernel versions, the two systems
are identical. It is seen that the scanner (and the disk) are
identified correctly in both cases, but for some reason
"sane-find-scanner" fails under 2.4.17. The sg module is loaded in
both cases. This looks like a bug in either the SCSI part of 2.4.17 or
a bug in sane.
Things work with 2.2.20, which means my problems are solved. I just
report this since it might be of interest. (Hopefully this is not
well-known already.) I will be happy to provide more information if
someone needs it.
B.t.w. could someone tell me the reason why the installation kernel
is compiled without hardware clock support?
