Re: Advansys driver freezes kernel

Thanks Brad.

What would it be likely to take to fix the driver?  I learned C a long time 
ago, but I am not an expert and I wouldn't have time to do a really major 
engineering project.  Would it just be a question of trawling through the 
source code and changing little-endian things into big-endian things in 
some kind of fairly obvious way, or would it be much more complicated than 
that?
