This issue is very rare, and has only happened to me maybe 3 times over the
past 7 months, each time being when I issued an LVM command
Has anybody experienced this before?
Yes. The message means just what it says. NMI is a hardware interrupt
usually reserved for machine errors such as an uncorrectable memory error.
In my case, it was a defective PCI card (with USB ports) raising the NMI.
(Which I determined by process of elimination.) Note that many system buses,
including PCI, have error checking and will raise NMI on failure.
I have heard of hardware that raised NMI in normal operation as a kind
of highest priority interrupt. However, such hardware is generally
equivalent to broken.
