Hi Ming,
I still see the call-trace with v5.5 (I passed through a NVMe
controller to a Linux VM running on Hyper-V and I'm testing VM
hibernation with some extra patches applied to the Hyper-V drivers).
It looks your Aug-2019 patchset
(https://lore.kernel.org/linux-block/20190812134312.16732-6-ming.lei@redhat.com/)
has not been accepted?
PS, this is the call-trace I'm seeing:
