@zyga: I'm honestly very surprised that the config change had that drastic an impact on the single-CPU system. Can you tell me what 'cat /sys/devices/system/cpu/possible' says on that system?
This was in a virtual machine with one CPU and the file listed above says:
cat /sys/devices/system/cpu/possible
0-127
Interestingly, using more CPUs (4 virtual CPUs) the numbers change to:
$ cat /sys/devices/system/cpu/possible
0-7
So it looks like a bug in the kernel or the VM software (in this case vmware).
I will give the new kernels a try and report back.
Hey Seth.
