Alexander,

Ultra320 was generally problematic. I worked on two different hardware
platforms that both gave up on the original plan of using 320 and went
back to an Ultra160 ASIC between prototype and GA. Mainly due to
signaling problems. Even internal controller to disk backplane cabling
was a problem.

So make sure your cabling and termination is in good working order and
rated for 320.

I don't have any SPI hardware anymore. But my suggestion would be to
look for an LSI 53C1030-based card. It's a different ASIC than the 1010
you tried (has more in common with the first gen SAS controllers). It's
the final generation of SPI products and would stand the best chance of
working.
