Hi, I tested the SD card feature in the past, but my RPi booted only 2 out of 3 times, and there were often routing issues. The recent update enabled this feature by default, and I started encountering missing files in Python (scripts or firewall-cmd), and apt reinstalls frequently crashed with a SEGFAULT. To resolve this, I had to disable it using dtparam=sd_cqe=off.
My SD cards might be somewhat faulty, but I hope this information helps someone. I’m using the Kingston Canvas Go! Plus microSDXC 128GB / UHS-I V30 card. It’s much faster with A2, but unfortunately not stable.![😔]()
