So it could be when memory consumption is over a certain percent, the bug will be triggered.

Bisected and at the commit "[04ce8955fbe4d84376b92b875c42942489fcf3c5]mm: page table check", the system still doesn't encounter any freezes.So it's not this commit that introduces the bug. Sorry for bothering.
