Anton, You're right. By defaut, the CONFIG_NR_CPUS is set to 32. I need to reset that and rebuild the kernel to try the interrupt binding again. Thanks,

Hi,

This is probably a ppc64 specific issue, we can continue this on linuxppc64-dev@lists.linuxppc.org

Its part of the support for > 32way machines, but it looks like its broken for some configurations (Im guessing you have CONFIG_NR_CPUS set to 32).
