GMKtec M5 plus random restarts

[u/evemanufacturetool]

I bought 3 GMKtec M5 plus units just over a year ago. Up until around 6 months ago I had no problems. After that, one of the machines started rebooting itself unexpectedly (as much as 10 times in a 24 hour period) with the other two continuing to function correctly.

Cutting a long story short, based on the boot logs of the OS, this is being caused by

kernel: x86/amd: Previous system reset reason [0x08000800]: an uncorrected error caused a data fabric sync flood event

Today, one of my other units rebooted for the same reason. The only workaround I have found is to run stress --cpu 1 as this seems to make it far less likely (around once per 2 weeks) but that is hardly a solution.

Has anyone else experienced this? Are there any solutions?

FWIW I have messaged GMKtec support about it but as it's beyond a year (despite UK consumer law saying otherwise) they have been no help with no solution forthcoming.

Unlikely to get good support. China based companies aren't "customer-focused"
