Well, I've finally gotten Tux up on the PowerPC 405GP embedded processor from IBM. The key problem is that the kernel patch is incomplete for the ppc architecture. It does not add an entry to the sys_call_table for sys_tux. Once I added this entry and changed _NR_tux in user space, it came up fine. If this needs to be added to the official patch, let me know. Though it's simple minded enough to fix IF you know what to look for. Jim
