In my case, just the power cycle was not sufficient. I had to also
change settings in BIOS [1], and only then it came back.
Even after reverting all settings to the same state as before.

I was hoping to fix this in Kernel, but I don't see a way forward.
If you have any other ideas or patches to test, send them my way!
I will gladly help.

[1] I turned off sr-iov, resize-bar & disabled "Bluetooth On/Off".
In a previous attempt, fast-boot and TPM were also disabled.

Thanks,
