So you're booting the generic kernel/initrd and the generic arm64 image on Pis? This is in no way supported and quite frankly I'm surprised that it even works.

Details are here: https://discourse.maas.io/t/build-your-own-bare-metal-cloud-using-a- raspberry-pi-cluster-with-maas/5845 However, using the same procedure on the same hardware but selecting ubuntu 21.10 always fails. This appears to be caused by curtin being unable to see the USB disk device /dev/sda to which we are deploying. The same issue occurs with all versions of the kernel available for 21.10. I enclose the log files downloaded from MAAS.
