Please could you also post the results of 'vcgencmd get_config int' plus 'grep Revision /proc/cpuinfo'

Thanks. I suspect the over-clocking configuration may be the problem. Does it still fail if you reduce the ARM frequency to 1800 MHz?

NOTIFY_XHCI_RESET should only be called after the PCIe fundamental reset is asserted which will cause the VLI to be reset. There doesn't appear to be a VLI 'software reset' mechanism...

It's worth making sure that the .dtb files are up to date, otherwise, Linux won't find the reset controller. https://github.com/raspberrypi/linux/blob/rpi-5.10.y/arch/arm/boot/dts/bcm2711-rpi-cm4.dts#L288

@juergh @procount Please can you describe the high-level use-case for needing to know the firmware / kernel boot devices vs the root filesystem? As @pelwell noted some information could be...

The firmware and bootloader and OS agnostic so would not translate Linux device ids. They also don't use partition UUIDs. It's more like index (as passed to sudo reboot), route-string...

Yes, on Pi3 you only get the partition number. It should be possible to map the boot-mode but there's no easy way to get the USB topology. Therefore I think...

This feature is now covered in the official documentation for firmware generated device tree nodes (/chosen) https://www.raspberrypi.com/documentation/computers/configuration.html#part4

IIRC Pi3 expects the Option43 response to come from the TFTP server not the DHCP server. If the DHCP server sets Option66 to the dotted decimal IPV4 address then that...
