Subject: BTRFS in 4.4.0-rc7 keeping system from hibernating
Date: Wed, 30 Dec 2015 17:07:58 -0600 [thread overview]
Message-ID: <568463CE.3060806@jons.org> (raw)
Hello,
Ever since 4.4.0-rc1 or so, BTRFS and XFS hasn't played well with
hibernation. It may be deeper down as both filesystems seem to have
issues with not being able to commit/freeze as can be seen below:

4.3.0 would hibernate correctly.
