Mine even stops ealier, while scanning IDE devices. 2.6.14.4 has been running stable for 4 days. For the long term, I'll probably migrate the box to 2.6 and leave it there. > So now we're back to the original problem, i.e. why does he get bad pmd > that often on 2.4.

It's been up for a few hours. I'll let it run for at least a week or two and will report back positive or negative results. After that, I'll try 2.4.32 with nosmp and acpi=off. -Chris - 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/
