It's ECC memory, I'd doubt it.

You're saying that I'll have to spend all the afternoon watching DVDs? Well, if the linux kernel needs it!

Yes, I run several "cat /dev/zero > /dev/null &" and they all kept in CPU #0.
I did a bitsection search and I couldn't found the culprit, apparently it is caused by a config option; now it works fine after switching off CONFIG_HOTPLUG_CPU and some ACPI options. Also, when it didn't work the CPU that would get all the processes could be CPU #0 or #1 - it changed randomly depending on the boot. - 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/
