I've found that how easy it is to reproduce varies somewhat - some versions it's triggered at almost any file manipulation, others I've had to copy a couple of large files around at the same time or otherwise increase disk access while moving large files - but I can reproduce it absolutely consistently in the versions listed above. I've noticed that in the affected versions I get large kswapd0 CPU usage spikes while copying files around even if it doesn't always get stuck at 100% usage indefinitely (though I can always get it to do that with sufficient provocation), while unaffected versions kswapd0 hardly shows up in CPU usage no matter what I do.
