Bug description:
For OEM-6.1
[Impact]
While doing some tests such as suspend/resume or CPU stress tests the system
would hang.
[Fix]
Below commit fixed the issue, but not going to be merged into mainline.
The patch is still under discussion and have other variance, and we already
merged the origin patch into oem-6.0 and 5.15/5.19 for a year, so could
consider it's safer for us.
https://patchwork.ozlabs.org/project/linux-pci/patch/20220705060014.10050-1-vid...@nvidia.com/
I also created a DMI quirk to make the patches only affects on listed
platforms.
[Test]
The affected machines could suspend/resume well.
[Where problems could occur]
The patches only affects on the listed platforms, and won't affect other
platforms.
======================================================================
For Jammy/Kinetic SRU
[Impact]
While doing some tests such as suspend/resume or CPU stress tests the system
would hang.
[Fix]
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.
[Test]
Verified on the failed machines and ODM also verified on their side.
[Where problems could occur]

[Test]
Verified on the failed machines and ODM also verified on their side.
[Where problems could occur]
The 2 patches look pretty safe to me, they try to preserve the ASPM state of
devices.
