The problem is that the system cannot find the root filesystem anymore. It seem this a particular issue with some older revisions of Raspberry Pi 4 (especially those with 4GB+ RAM, like those ending in “B0T”) leading to MMC timeouts and failure to mount the root filesystem.

Fix

If you have For RPi 4 model with 4GB+ RAM, a common workaround is to edit the config.txt file in the EFI partition of your SD card. Add the following line under the [pi4] section: total_mem=4015.
