I have been trying to PXE boot Ubuntu 20.04 server lts for the rpi4 since about a week now, and I am basically stuck at the point where /init is executed and the boot process basically stalls. I can't find any clue as to why it hangs there. It looks as if init doesn't know where the rootfs is, but I could be wrong. The rpi 4b IP can be pinged after the boot process is stalled, but I cant ssh into it. I am wondering if I am stuck into some kind of u-boot stage. Unfortunately the serial console doesn't give out any output past the point where the boot process hangs. I have sort of been following this guy indications but some steps do look truly unclear to me. NOTE: NFS exports in question can be mounted fine.

Setup info:

TFTP + NFS server is 172.12.1.1; RPI 4b static lease IP is 172.12.1.51
