Found the answer to my own question. The problem was lurking
in /usr/src/linux/include/linux/modules/scsi_syms.ver .
It needed to be remade and the sequence:
make mrproper; make xconfig; make dep; make clean; make bzImage ...
did the trick. I haven't used "mrproper" before so it does have
some use!
Did some timing on the existing "sg" driver with 4K buffer size:
60 seconds to read 40MBytes
and with 2K buffer size:
120 seconds to read 40MBytes
[P166MMX 64Mb, Seagate ST31230N, Advansys 940U PCI adapter]
It seems as though the per command time swamps the data transfer
time. I hope that the throughput will be substantially better
with the addition of scatter lists.
