emanuele-f Posted April 29, 2022 Posted April 29, 2022 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 0 Quote
Werner Posted April 30, 2022 Posted April 30, 2022 Sounds more like a degraded sd card. With the information given reproduction is basically impossible since nobody has a second sight about what is going on. So I have my doubts that this gets addressed. 0 Quote

After another week of usage no problems to report with the legacy kernel.

targa Posted July 27, 2022 Posted July 27, 2022 (edited) I happen to have similar problems (ssh sessions suddenly "gone", only recoverable by power-cycle with a 35% chance that it comes up.) I connected a serial console and got some kernel errors, so I saw, eg. during boot, those errors show up at the after the same [OK] lines, I suspect this to be a kernel problem as well. I could supply more information if guided. /To [ OK ] Started udev Kernel Device Manager.

emanuele-f Posted September 21, 2023 Author Posted September 21, 2023 Recently the `linux-dtb-legacy-sunxi64` package has been updated to 23.8.1, which uses kernel `5.15.127-legacy-sunxi64` and freezes started to happen again. To address the issue, I've used armbian-config to downgrade to `linux-image-legacy-sunxi64=21.02.3`, which has kernel 5.4.88, and board is running fine again now. 0 Quote
