            Bug ID: 271888
           Summary: NVME polled command failed to complete within 10s.
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: emaste@freebsd.org

Testing on some experimental hardware I observed a panic with the subject
above. With a patch to turn the panic into a printf I can see:

nvme0: <Generic NVMe Device> mem 0xb6300000-0xb6303fff at device 0.0
numa-domain 1 on pci19
nvme0: RECOVERY_START 12364819237 vs 8907038712
nvme0: Completions present in output without an interrupt
NVME polled command failed to complete within 10s. <- downgraded panic
nvme0: nvme_ctrlr_set_num_qpairs failed!
nvme0: failing queued i/0
nvme0: SET FEATURES (09) sqid:0 cid:0 nsid:0 cdw10:00000007 cdw11:007f007f
nvme0: ABORTED - BY REQUEST (00/07) crd:0 m:0 dnr:0 sqid:0 cid:0 cdw0:0
