I suspect that that is critically dependant on the version of the compiler (and possibly other toolchain elements) used for the kernel. Your earlier comment about optimisations might be relevant- has something changed in the compiler defaults or SPARC code generation during Sarge's lifetime? My experience is that a SuperSparc-based SMP SS20 is rock-solid with 2.4.27 as shipped. Compiling 2.4.3x for a sun4d- which should in principle work- sometimes results in a kernel that will run long enough to recompile itself, other times one of the CPUs locks up during init: I've not had time to try to track this down in greater detail but I'm fairly sure it's to do with the exact version of gcc etc. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
