I have a general purpose, single-node server, which randomly ends up frozen under heavy load, when using kernel 6.2, usually when full backups are running. Woke up to below message this morning.
This server was originally installed with proxmox 7.x, and operated flawlessly. Later upgraded to proxmox 8.0 with kernel 6.2 Random kernel panics started then. Downgrading kernel to 5.15.x seem to solve the issue and had no kernel panics or hard lock-ups under kernel 5.15
Took advantage of a recent update/reboot to switch again to the latest 6.2 kernel, and a day later happened again.
any thoughts?

Code:
