While doing some tests such as suspend/resume or CPU stress tests the system would hang.
The 2 commits fix the issue, but still not get accepted yet.
So, I created a DMI quirk to make the patches only affects on listed platforms.
Verified on the failed machines and ODM also verified on their side.
[Where problems could occur]
The patches only affects on the listed platforms, and won't affect other platforms.
