[Thanks for catching all my typos]
No. It works fine for me. Well, occasionally, it fails to swap out a page, but nothing like you have here.
Could you try to trace it? I used script like below after mounting tracefs. You may want to comment out all tests but a failing one.
#!/bin/sh -efu
echo > /sys/kernel/tracing/trace echo 1 > /sys/kernel/tracing/events/huge_memory/enable
while ./khugepaged; do echo > /sys/kernel/tracing/trace done
cat /sys/kernel/tracing/trace
