will transparent_hugepage=madvise be saner so that apps that do benefits from transparent hugepages and explicitly asked for it can have this feature available? unfortunately, i have no idea whether cp and mv are using these features. ;-)

best regards,

I don't think any of our applications uses MADV_HUGEPAGE. I've also read this is just for embedded devices, where it is important to conserve memory. If disabling THP fixes this, maybe the memory compaction system is at fault, which I believe gets enabled together with THP.
