Hi, that stepping shouldn't be important but thanks for checking. I tried to find a few avx/fma test programs, but I only found super small ones and none triggered anything like your freeze.
Since you have currently the only setup to trigger this, if you can you could try the far newer qemu/libvirt that is in Ubuntu Zesty (current release in development), but that is grasping for straws. What we really need is something we can reproduce this on :-/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1654271 Title: host machine freezes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1654271/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
