Subject: Re: [PATCH 2/3] mm: page table check

Here is the config:

I can't stably reproduce the bug, but it seems it's likely to happen 
when a music is playing in the background or there is a file operation.

I encountered it again on linux-next-20211126 when I was trying to 
extract a rar file, and the sound is constantly repeating when my system 
freezes, but nothing useful in journalctl.
