Make sure that if you are using > 2.4.x you have ACPI disabled and see it looks any better Correct, and I came to the same conclusion ; Chris told us he booted with the "nosmp" option. I've checked his config, and he has CONFIG_ACPI_BOOT=y. I've just tried the same here, and I confirm that my machine (dual athlon) does not boot with "nosmp" unless I also add "acpi=off". Mine even stops ealier, while scanning IDE devices. So now we're back to the original problem, i.e. why does he get bad pmd that often on 2.4. It leaves us with the following possible next steps after the problem occurs again (if it still happens with 2.6.14 or if Chris is OK for a few more tests) : - 2.4.32 nosmp acpi=off => the easiest one - 2.4.32 + aic7xxx+20040522 => the more interesting one Regards, Willy - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
