I think this should be fixed by 5.5 commit:
commit 284efb473ef5f02a7f2c13fdf8d516ecc589bdf1
Author: Lorenzo Bianconi <[email protected]>
Date: Mon Oct 28 17:38:05 2019 +0100
mt76: mt76u: rely on a dedicated stats workqueue
and if it indeed fixes the problem, this commit should be requested
to stable.
