I can confirm that the issue looks fixed using 3.13.0-44.73~precise1 from precise-proposed.
I made more than ten reboots with the new kernel installed on VMs and all were successful. Then I switched back to the previous 3.13.0-43.72~precise1 and VMs boot failed at the first trial. Again back to propose 3.13.0-44.73~precise1 at VM were booting fine. I'm not using Trusty on these AMD machines so I cannot test it. But the kernel is the same as precise so the issue should be fixed also on Trusty. ** Tags added: verification-done-precise -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1379340 Title: qemu-kvm guest panic for AMD smp trusty guests To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1379340/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
