(In reply to Michael Dexter from comment #0)
The text dump shows that there're lots of `160456931108421470xx` from output of
`vmstat -m`. That is 16045693110842147038 ( or 0xdeadc0dedeadc0de ) + some
offset.

It appears the kernel is accessing from / writing to un-allocated pages, and
results in corrupted memory.

To be clear, is that the host but not the VM freezes ?

Does older 15.0-STABLE or 16.0-CURRENT work good ?
