Comment 2 Andrew Jones 2014-07-14 09:44:42 UTC 
A comment in the kernel source above this warning says

/* If we get here, not a certified SMP capable AMD system. */

So you've likely configured your qemu machine's cpu topology in such a way that the kernel doesn't know what to do with it. Take a look at your qemu command line, as the fix should be in that configuration. Please paste the command line here as well.

This bug is being closed with INSUFFICIENT_DATA as there has not been a response in over 3 weeks. If you are still experiencing this issue, please reopen and attach the relevant data from the latest kernel you are running and any data that might have been requested previously.
