[1] is very straightforward on it: Use vendor hardware diagnostics software to analyse system health. Contact the hardware manufacturer for further assistance. So yes, you may have faulty hardware. > The motherboard/CPU is still under warranty, so if it is hardware related, I > suppose I'll have to have someway to prove that to the manufacturer. Relevant parts of dmesg should be a valid starting point. If possible, try a different kernel (from the backports, for instance). If it's a hardware - you'll have these NMI interrupts too.
