Hello, I'm experiencing system hangs and kernel oops on Fedora 19. Everything happens when I restart guest system inside qemu/kvm container. My system becomes unstable on kernel 3.9.5 and totally hangs on 3.9.6 and later. It happens just after guest OS (latest stable Debian Linux) shows grub boot menu. I sometimes see text console with kernel oops message on my bare hardware but never had time or will to write it down on paper. I can't provide more details right now, because nothing gets written to system logs (serious oops?). Besides this issues all other pieces of my box are working perfectly. I need some instrumentation and guidance finding what is exactly going wrong.
