That's my view on the fpswa printk's (handle_fpu_swa): they are normal, expected, and there is absolutely nothing that can be done about them -- so why print a "warning" about them (even if it is only 5 per second)? If nothing else, toggle the meaning for IA64_THREAD_FPEMU_NOPRINT: turn it ON for special apps. Rate-limited unaligned loads in user space make a lot more sense, since they _may_ point out issues in the code. Kevin
