[Bug 632616] Re: Scheduler does not max all cores after suspend/resume

[Greg Olson]

I've got a Lenovo W510 with I7-Q720, and can confirm this behavior. Easy
to test using the 'stress' app (available in Ubuntu Software Center).
After boot, stress -c 8 pegged all "cores". Suspend/resume. Run same
program with same args. No matter how many "workers" you specify (via
-c), only one core will be busy.
