Hello,

I recently purchased BeeLink ME mini PC and I am experiencing random system freezes. I was finally able to capture a kernel debug output. The system runs Linux (TrueNAS SCALE based on Debian 12, kernel 6.12.15).

Debian GNU/Linux 12 truenas tty1

Key points:

The freeze occurs randomly: sometimes after a few hours of uptime, sometimes only after a couple of days.

When the freeze happens, the console shows a kernel crash:

general protection fault, probably for non-canonical address
RIP: __purge_vmap_area_lazy

The crash occurs in a kernel worker thread (kworker) while handling memory management tasks.
I noticed messages from the Intel GPU driver (i915), such as:
[drm] *ERROR* CPU pipe A FIFO underrun
but from my analysis these seem unrelated to the actual crash.
No NVMe drives are installed in the system at the moment, so storage drivers are not involved.

The same random freezes were also observed when testing with Proxmox 9 (Debian 13), immediately after installation, without running any VMs or containers.

This suggests a potential hardware issue (e.g. memory or motherboard), but I would like your assistance to confirm.

Could you please advise on the following:

Are there any known compatibility issues of this mini PC with Linux kernels (especially with Intel Alder Lake iGPU / i915)?
Could this be caused by faulty RAM or BIOS/firmware bugs?
Are there recommended BIOS updates or configuration changes to improve Linux stability on this model?

Thank you
