I didn't notice this, I'll fix it in updated patch.

I'm adding some logging in pci.c around rtw_pci_shutdown(),
maybe the chip's power or reset state is just stuck before rtw88*
reaches it and USB for some reason leaves it that way. Let's see if the 
PCIe function even reaches D3hot transition.

Could you redo a warm reboot with only the updated patch and attach the
previous and current logging same as before?
Could you also attach your acpidump? I'd like to see if D3cold state is
possible which may be a possible fix.
