Good, someone with a system other than MVME16x using an NCR53C710 :-)

>From your dmesg:

scsi-ncr53c7xx : NCR53c710 at memory 0xd0190040, io 0x0, irq 12

This is the old ncr53c7xx driver, I believe it is broken on prepackaged
Debian kernels because of a bogus virt_to_bus() call and/or the kernel
being compiled with CONFIG_SINGLE_MEMORY_CHUNK=N. On early 2.4 kernels
it did still work for me, but hasn't worked since 2.4.x (I don't
remember x).

I will try to rewrite the amiga7xx driver this evening to use the new
53c700 driver core. Should be pretty simple since it already works on

It would be nice if you can test it, if it works I think we can safely
get rid of the old ncr53c7xx driver.

Kind regards,
