Yes, you are right. At the commit 
"[1e67abff1820489435aad3fcf258708c21c283ef] x86: mm: add x86_64 support 
for page table check" my system starts to experience the freeze.

I can now reproduce the freeze by following the steps below:

1. Open 20 YouTube video pages, and a YouTube Music page.
2. Play music in the background. (The step can be omitted)
3. Run `git clone 
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git ln`

git will never successfully clone the repo because the system will 
freeze during the operation.

I also tried adding `page_table_check=off` to the boot option but still 
experienced the freeze. Perhaps the option is of no use.
