But it is not the patch we should blame. :-) This problem happens on CPU0 because of broken bios.. refer to the thread: http://lists-archives.org/linux-kernel/27303845-kvm-activate-virtualization-... Could you please update your bios and try again? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
