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.

This commit by itself would not cause the freeze or BUG_ON(), but the
next commit which enables it on x86 arch might.
