Although running on the same kernel binary the initrd changed greatly when upgrading, so ordering/timing between those two is off. Note that the dmesg output is captured right after boot. I think I remember seeing a "TSC unstable" message pretty soon after boot, but I might be mixing it up with my other AMD-based KVM server. I don't hold normal (non-boot) logs that long, so I can't tell for sure. If you need any more info feel free to contact me. Bernhard
