Proxmox VE 7.0-11 seems to require BIOS Update on NUC8i5BEH

[TurboAsterix]

Hello,

I am running about seven VMs in Proxmox VE 7.0-11 on an Intel 8th generation NUC8i5BEH (Product Code BOXNUC8i5BEH2).

Proxmox 6.x was running rock solid for like 2 years, however 7.0 seems to freeze the NUC reproducible after an arbitrary uptime between 2 min and 30 min.
The system runs headless, but with regards to syslog (just stops, no messages) and no HDD light at all it seems to freeze the entire system (not just a NIC issue).
The VMs as well looked frozen - at least not reachable via network.

At first sight It looks like a typical RAM issue but the freezes were directly related to the upgrade to VE 7.0.

My NUC still ran the original BIOS dated 06/18/2019 version BECFL357.86A.0073.2019.0618.1409.
After upgrade to BIOS dated 06/21/2021 version BECFL357.86A.0089.2021.0621.1343 (short version 0089) it seems the freezes are fixed.
Right now the uptime is > 2 hours without freezes.

Maybe something funny with Kernel 5.11 and the NUCs.

My issue is solved, but this might help others that encounter this issue as the NUCs are pretty often used in Home Labs.

Best regards,
TurboAsterix

Same problem at B550 Motherboard with R5 5600X
Mem-Test is without Error.

System:
R5 5600X
BioStar B550M Silver 5.x( B55BS730.BST (newest Beta, got it via Support)
GTS 450 (only for install process)
4 x 32GB 3600 (tested with and without XMP)
SanDisk Ultra II 960GB

ISO:
proxmox-ve_7.0-1.iso

Wanted a fresh Proxmox install, used 3 different USBs with Etcher install.
Sometimes it hangs while entering the password, sometimes later at the installation process (between 51% - 52% progress)
No BIOS-Update for this Board to fix the problem.

Sorry, Main-Language is German.


Edit:
Installed Proxmox now with a separate Ethernet-Card, via Debian 10 > Proxmox 6.4 > Proxmox 7.0.1
