Thanks Jean, here are info you asked.
Could I ask what is it about? The warning in kernel log or the host
freezing issue?
If it's about the former, I should mention that in the log I posted, I
have already applied a local patch (sent in a separate thread with you
involved) that reserved one more page in e820.
