Well, I have been fighting a similar issue for several months now,
albeit with multipath enabled. Haven't had much progress with this,
sadly.
Seeing that this is our distro kernel it might or might not be
related; however, as the symptoms are identical there still is a
chance that this is actually a generic block-layer problem.
