Comment 24 for bug 1178707

Looking at the dmesg snippets of the various kernels there seem to be multiple pages that have that bad page state. The locations seem random (maybe visualizing may yield some pattern). It happens the same with the ec2 kernel and the virtual flavour which actually are very different in the Xen code.
So I am wondering whether the external factors. Is this happening to all instances used? Is there maybe any pattern when looking at the availability zones, the Xen version (dmesg in the guest) or the visible cpu info (/proc/cpuinfo in the guest)? The instance should remain where it was before if it is only rebooted.
Although the report says multiple instance types (which are?) and that would lessen the chances of some odd hw problem on the host as I think I was told each host only serves instances of the same type...
