Can you please test the following patch, which should address the root cause:
https://lore.kernel.org/linux-acpi/20201201213019.1558738-1-furquan@google.com/ (local)

It also helps another AMD laptop on S5:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1912935

No, this patch doesn't help on ThinkPad AMD platform.

Thanks for the confirmation!

Mathias, want me to take this in my tree now, or are you going to send
me more patches for 5.12-rc1?

Nothing more for 5.12-rc1 from me.

Could this be a PCI quirk instead of xhci?
Maybe there is some PCI flag for this already, haven't checked yet.

We want a specific PCI device to go to PCI D3cold at PCI shutdown...

There probably is.  Kay-Heng, can you look into doing that instead?

There is no such PCI quirk, usually it calls driver to shutdown.

Regards,
Aaron

thanks,
