Some of the 440Mhz boxes did roll CPU HW version after initial release - including some SMP bugs that C3K wouldn't be exposed to. I'm skeptical it's a bug in the FPU unless you can demonstrate the same code works on another (newer) CPU model. thanks, grant _______________________________________________ parisc-linux mailing list parisc-linux@lists.parisc-linux.org http://lists.parisc-linux.org/mailman/listinfo/parisc-linux
