Hi, thanks for the answer - unfortunately I still have the same problem. I have tried both the code from CVS and the versions 2.7p39, 2.8p1 and 2.8p3 all with the same result. owhttpd and owfs are crashing (see my first post below) when I try to access the BAE 910 chip.
I'm not running the normal kernel on my server as Ubuntu server edition is compiled with PAE and my CPU does not have this addressing feature - can this be the cause?? As I'm not a skilled C-debugger so any help is mostly welcome.
