Random, hard freeze. Can't diagnose it and REISUB doesn't help

Might be a kernel issue. Try updating the kernel. Have a look here.

System Freezes randomly

Hey guys! Hope y’all are doing well. After installing the update from 04/09 my system started crashing randomly. It really does not have a pattern - I can be playing, scrolling through Facebook, coding, etc; It just freezes. No commands will work, have to hard reset/power down the hole computer. At first, I thought the problem was related to some Iommu errors (like this one) pci 0000:00:00.2: AMD-Vi: Unable to read/write to IOMMU perf counter. But then I realized those are related boot error…

Worked for me & others.
