The cause of this bug and the related fix is available in https://github.com/armbian/build/pull/11232 . As temporary workaround until the patch is merged and the fixed kernel image is available: compile the attached dts with `dtc -@ -I dts -O dtb -o cpu-supply-fix.dtbo cpu-supply-fix.dts` or use the pre-compiled dtbo attached create the /boot/overlay-user folder if it does not exist place the dtbo at /boot/overlay-user/cpu-supply-fix.dtbo add user_overlays=cpu-supply-fix to /boot/armbianEnv.txt reboot the board To verify that the patch works: on boot, the serial console should print Applying user provided DT overlay cpu-supply-fix.dtbo cat /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_max_freq should print 1008000 openssl speed -multi 8 should now run for several minutes without freezing the board (before the fix, it failed in under 1 minute) cpu-supply-fix.dtscpu-supply-fix.dtbo

Sorry for the minimal info provided in this report but, due to the possible data corruption which the bug may cause, I'm not willing to reproduce this again on my board which runs in production. One week ago, I experienced data corruption happening on the nanopi. Actually it was some time (more than one month) that I saw the board acting weird: - long ssh transfers would sometime brake (via https://github.com/dooblem/bsync) - `apt update` reported invalid keys for the official armbian repository - on rare occasions, the board would freeze (not respond to ssh, requiring manual power cycle) After experiencing data corruption, I though the board was broken but decided to switch to the legacy image via `armbian-config` as a last resort. When running `armbian-config` and selecting "Other" to switch kernel, the kernel crashed. I tried again and I was successful. With the legacy image `5.4.88-sunxi64 #21.02.3` the board works great, and all the reported issues do not occur any more. So it seems like there is a bug in the "current" image (it should be version 5.15.25), possibly in a module linked to the encryption. This is all the info I can provide for this report. Hope it helps
