It's already in there in fact. It wasn't originally, until we discovered that there is no way to output a message in head.S when you're using vesafb. The only way to give a visible error is to do it before the video switched. The old test was kept, although it's redundant. This means Vivek/Eric added it now to the SMP trampoline and ACPI S3 resume too, but there it is technically redundant too. But you have to spin, otherwise the user cannot see what is wrong (and that is much more important than your obscure possibility of automatic fallback -- inserting the wrong CD is pretty common) Finding panic=.. would require writing a command line parser in 16bit assembly. I have my doubts that's a good use of anyone's time. -Andi (who wonders why he wastes so much time writing about this thing) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
