What is your test scenario? Who or what has these pages isolated that is allowing too_many_isolated() to be true?
I have a test app that attempts to create fragmentation. Then I run echo 1 > /proc/sys/vm/compact_memory That is all. The test app mallocs 2MB 100 times, memsets them. Then it frees the even numbered 2MB blocks. That is, 2MB*50 remains malloced and 2MB*50 gets freed.
