Sorry for breaking in upon that, and thank you for responding even so.

I'm still clinging to your 0.1% possibility that it was not the
intended kernel running.

Anyway, I'm not going to worry about it further, until we see another
hit - please do keep the VM_BUG_ON in your test kernel (i.e. resist
that temptation to race in from your vacation to apply today's patch!),
even though the right thing for 3.7 was to remove it.

Thanks,
Hugh
