I have a Gigabyte GA-z170N-WIFI (32GB memory in two 16GB modules) board that refuses to boot, When booting to real media (I.e. Ubuntu 18 live install CD or it's installed OS on SDD) it freezes at various points. Sometimes a kernel panic, sometimes it hangs...and it has even hung while working in the CMOS setup.

The mainboard was just replaced, but the it has the same problems as before it was replaced.

I managed to get it to boot to and run memtest ...which reported no errors.

The only consistent error I get is when I try to boot to stresslinux_64bit_11.4 - where it consistently hangs at the message...

NMI watchdog enabled, takes one hw-pmu counter.
#3

Screenshot

Attempting to variations of text only knoppix either results in hangs, or kernel panics.

boot: knoppix 0 = hangs
boot: knoppix 1 = hangs
boot: knoppix acpi=off = kernel panic
boot: knoppix acpi=off noapic nolapic = kernel panic
boot: knoppix acpi=off noapic nolapic pci=bios = kernel panic

Is it safe to say this is a bad CPU?

In our case, it was a bad processor. Replacing the CPU resolved the issue. Posting here for other's reference.
