Probably bad RAM. [19535.801872] Run memtest86+ or a similar memory test tool. Is it possible this was a decrement-after-free bug? It could also be bad RAM I suppose, I was using this machine to do some pretty intense DRAM RAPL validation which involved a lot of DIMM swapping so it is conceivable that I managed to break something. Also lots of [ 4714.797333] perfevents: irq loop stuck! errors as always, I think we decided those were probably a hardware issue.
