What happens if you run several infinite loops to increase the load?
Does everything still stay on CPU0?
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.
If you can report those configuration options and the symptoms in a
new thread to lkml that would be helpful. Also if you can work out
when it started happening, that helps too.
Thanks,
Nick
