See my previous comments (updated) for [[https://bugs.openwrt.org/index.php?do=details&task_id=3099#comment9712|ongoing test results]] and [[https://bugs.openwrt.org/index.php?do=details&task_id=3099#comment9729|hardware serial console setup]].
I've made a custom build of the OpenWRT 21.02 branch with kernel symbols and other debugging information compiled in. No luck with stress-ng so far, but a backup was queued to happen and I got another crash - this time with more information!
I've temporarily switched back to master branch snapshot to let the backups finish successfully, then I'll work on backporting the CPU governor patches to the 21.02 branch to see if that fixes these crashes.
