I verified my guess through providing a kernel parameter at startup

where the bit set is along xhci.h:
  #define XHCI_SLOW_SUSPEND BIT_ULL(17)

This quirk provide nearly the same as the patch mentioned in #5.

With kernel 5.3.0-28 and this parameter set the machine suspended without complaining :-) Unfortunately it did not resume :-(

With kernel 5.0.0-37 and this parameter set the machine suspended and resumed without complaining.

Since I misused the kernel parameter this maybe a side effect. If not it is a previously covered bug. This will be a new game.

Again: If there is a kernel available with the patch applied I'm willing to test the patch.
