@onlyjob I believe it's due to that the dm-writeboost is bit old. The issue is fixed in 2.2.6. I should have written in the ChangeLog that I've fixed the issue with 4.8 kernel by the issue #160.

see the commit

OMG I've forgotten to upgrade dm-writeboost on this machine... Sorry, Akira. Everything is OK...
