I mentioned before, that I have problems using my Apollo 700 (9000/720) with the Linux here. I build a new cross tool chain and a new kernel + palo (all from 13.Jan 2001) but I always have the problem of looping error code: handler_interruption() pid=1 command='init' or whatever my first process is. I have instrumented the kernel code and added the output of the code number (a good idea to have this fix in the kernel !) and I saw: code=18 So I have the code 18 (decimal). In the PA RISC 1.1 manual (your link) I saw following description: 18 Data memory protection trap / Unaligned data reference trap So what does this mean here. An alignment problem ? Why is this code not handled in the switch/case ? I always use (I think the 32bit code). Have I set to a parisc64 ? How can I influence this ? Which kind of CPU is this in the 720 model ? (I know a 50MHz PA RISC ..) I hope anybody can help here Christoph ------------------------------------------------------------------------- private: christoph.plattner@dot.at company: christoph.plattner@alcatel.at
