I'm not a domain expert, but that panic really looks less like an LZ4 problem and more like a hardware fault/error.

Agreed. While executing lz4 code, an interrupt occured. The interrupt is totally unrelated to lz4.

You should check fmdump because it sounds like you have a hardware failure. If it isn't a hardware issue, let us know!
