Yes, QEMU 6.1 has a regression

     hw/pcie-root-port: Fix hotplug for PCI devices requiring IO

Although I can't say I really understand why that commit triggered it.
It caused the firmware to always allocate I/O space for every port
and there's limited total I/O space, so it runs out at 15 devices.
alternatively instead of reverting to native PCIe hotplug as in the issue
Daniel's mentioned, you can apply following fix
