Ok, this sounds good.

So, maybe the tool should be taught to always skip poisoned pages due to
danger of follow-up MCEs and, when kexec has rebooted due to an MCE, to
warn before doing a vmcore dump that the dump might not contain useful
information or that the dumping itself could result in further MCEs and
whether the user still wants to proceed.

Or something to that effect.

Thanks.
