There was also an issue with Linux about 8 years ago where the THP daemon would start busy-looping searching for pages to amalgamate, wasting loads of CPU time (and I believe freezing the processes it was inspecting), and so people were advising switching off THP for that reason until it was fixed. It hit our large Java processes quite badly.
