Background story: A couple of days ago, my Minisforum HM90, which was running Proxmox 7 at the time, started to randomly lock up. While the hardware itself seemed to be powered on, the software wasn't responding. After two days of troubleshooting, updating, switching to another distribution, changing RAM and SSDs and sometimes getting logs, and sometimes not getting logs at all, I was fed up and ready to never buy hardware from Minisforum again.

So I emailed the support, describing my situation and requesting a new device. Luckily, my HM90 was still within their 2-year warranty. Some Google searches brought up that they would most likely need to replace the device as there was no real solution.

48 hours later, I received an email asking me to change some BIOS settings. So far, everything has been up and running for 20 hours without issues. Compared to crashes every 90 minutes on average, that seems like a significant improvement.

Settings:

Deactivate the following in the BIOS

Advanced/AMD CBS/CPU Common Option/Core Performance Boost

Hopefully, this will be helpful to someone facing a similar situation.
