--- Comment #58 from stan <freebsd-...@mailden.net> ---
following my comment #57, here more debug info in another context with same
hardware :
I am able to boot TrueOS-Desktop-201803131015 with
`hw.nvme.per_cpi_io_queues="0"` set in /boot/loader.conf. Everything works
well, BUT fatal error comes when trying to resume after s3 suspend mode :
I see kernel messages ending with :
```
(…) kernel: WARN_ON(…stripped…) CSR SSP Base Not fine
(…) kernel: CSR HTP Not fine
(…) kernel: WARN_ON(…stripped…) Clearing unexpected auxiliary request for power
well 2
```
then :
```
nvme0: resetting controller
nvme0: controller ready did not become 0 within 30000 ms
nvme0: failing queued i/o
nvme0: READ sqid:1 cid:0 nsid: 1 lba:324015968 len:20
nvme0: ABORTED - BY REQUEST (00/07) sqid:1 cid:0 cdw0:0
```
and similar errors repeated a dozen times,
then the fatal :
```
nvd0: lost device - 0 outstanding
nvd0: removing device entry
nvme0: WRITE sqid:1 cid:0 nsid:1 lba:4416948 len:48
nvme0: ABORTED - BY REQUEST (00/07) sqid:1 cid:0 cdw0:0
