Could this problem be not specific to virt envs.? Anybody else seeing it?
I could only guess that on bare metal SMI or other firmware issue may interfere with AP boot. Could you test if this patch-set fixes issue for you? And do you see the same problem during suspend/resume (assuming that it's booted without problem)? -- ----- Igor -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
