There are some AMD GFX cards (such as WX3200 and RX640) that cannot be
used with Intel AlderLake based systems to enable ASPM. Using these

cards as video/display output, Intel Alder Lake based systems will hang
during suspend/resume.
Please reflow for 75 characters per line.
Also please mention the exact system you had problems with (also
firmware versions).
Add extra check to disable ASPM on Intel AlderLake based systems.
Is that a problem with Intel Alder Lake or the Dell system?
Shouldn’t ASPM just be disabled for the problematic cards for the
Dell system. You write newer cards worked fine.
There is a problem with Dell system (Dell Precision DT workstation),
which is based on Intel Alder Lake.
ASPM works just fine on these GPU's. It's more of an issue with
whether the underlying platform supports ASPM or not.
At least you didn’t document what the real issue is,
You can refer to bug tag from the comment messages.

that ASPM does not work. With current information (some GPU graphics
card with the the Dell system and others don’t), it could be the GPU,
the Dell system (firmware, …), a problem with Alder Lake SOC, or
another bug. I hope you are in contact with Dell to analyze it, so
ASPM can be enabled again.

Kind regards,
