Dr. Sudhir Kumar forced the electrons to say:

Maybe this is the problem? The sx.txt file talks
about a program called sx_firmware, downloadable at
ftp://ftp.bitwizard.nl/specialix/sx_firmware_<version>.tgz. Maybe that
is more appropriate for the card, module and kernel that you are
using. Nowhere in the documentation does Wolff talk about an sxboot
program.

Or are these two the same? I doubt it.

The only reason I can think of for this error is initialization problems.
That is why I suspect the sxboot program to be the root cause of all your
troubles.

Which is fine. They are logged by the kernel onto the console. You
can tweak the kernel logging options by diddling with the numbers in
/proc/sys/kernel/printk (more about that later).
