Another interesting point from looking over those bad files is that it is
only ever the first part that fails - the extended I/O stats are always fine.

For one of those failing cases, could you send through the .full file also?
I'll keep digging into it once I have that, thanks (no failures here FWLIW,
anything interesting about those VMs btw?  32 bit only, anything like that?).

thanks.
