Looking for known working/not working status of mender on Raspberry Pi CM4 (Compute Module 4)

- I tried one of the Raspberry Pi 4 downloads from [Downloads | Mender documentation](https://docs.mender.io/downloads#disk-images) (Actually the links are broken in there atm)

- was able to boot into linux kernel but ended with a message “Cannot open access to console, the root account is locked.”

- I tried mender-convert of a working Raspberry Pi CM4 disk image  
It only got one line into the linux boot with an error “brcm-pcie fd500000.pcie: link down”

Is there a known issue with Raspberry Pi CM4 “debian family”?

I see an article [Integration of Mender to reTerminal](https://hub.mender.io/t/integration-of-mender-to-reterminal/4361?utm_source=Mender.io&utm_medium=blog) relating to a Yocto build with Mender for RPi CM4.
