[T14 Gen 3 AMD] Fail to suspend/resume for the second time

[Nobuto Murata]

I had a similar issue before:
https://bugs.launchpad.net/ubuntu/+source/linux-hwe-5.19/+bug/2007718
However, I haven't seen the issue with later kernels until getting 6.8.0-11.11+1 recently.

* 6.8.0-11 - fails to suspend/resume for the second time although the first suspend/resume works
* 6.6.0-14 - no issue in terms of suspend/resume

One thing worth noting is that connecting an external monitor or not might be a key to trigger this issue. I cannot reproduce it when an external monitor (through USB-C to HDMI) is not connected.

kernel log when trying suspend/resume twice in a row. The machine got frozen while the power LED is still on in the second suspend and there is no second "PM: suspend entry (s2idle)" in the kernel log.

Multiple suspends in a row worked without an external monitor connected, but after connecting it the machine failed to suspend/resume.

Random pointers although I'm not sure those are identical to my issue:
