Adding Chuck, Neil and Chris from the bug report here [0].

With the above applied to v5.15.y, I am seeing suspend on 2 of our
boards fail. These boards are using NFS and on entry to suspend I am now
seeing ...

Freezing of tasks failed after 20.002 seconds (1 tasks refusing to
freeze, wq_busy=0):

The boards appear to hang at that point. So may be something else missing?
