I finally had a chance to test the ipipe-2.6.30-powerpc version from the git repository. Unfortunately, I noticed that our application dies after some time and that this behaviour is related to that alignment patch (if I take it out everything runs fine for > 2 days). Currently I'm investigating the reasons for that crash. It has something to do with floating point registers not being restored properly. Our alignment exceptions are mainly triggered by accesses to unaligned floating point data.
