Hi,
I'm having the same problem with two 4SE boards with 32gb emmcs installed with Armbian 23.02.2 Bullseye with Linux 5.15.93-rockchip64.
Seems to be some sort of driver issue that appear on heavy write activity to the emmc (apt upgrade or when using dd write test ) . Image was installed onto emmcs using armbian-install. Have also tried directly imaging emmc using usb adapter with same result.
Have been testing to try and work out cause (no result, I'm just a linux hack, by no means a expert) seems if I slow CPU down problem becomes less of an issue.
kern.log dump:
Eventually, with enough IO errors, system remounts into read only.
Haven't extensively tested yet, but haven't seen same problem using Radxa images (have tried Debian 4.4 and 5.10).
