First, let's start with pciconf -l of the nvme drive.= I have a strong idea, but need some data.

=C2=A0

While already provided privately with some other data, he= re for the public so that people are aware that currently there is an issue= with such drives:

nvme0@pci0:5:0:0: class=3D0x010802 rev=3D0x00 hdr=3D0x00 = vendor=3D0x144d device=3D0xa809 subvendor=3D0x144d subdevice=3D0xa801

Yea, so far this is the only re= port I've received, and there's not enough data in it to reproduce = it with any of the dozen NVMe drives that I have, or to spot a difference w= ith what I know I check in the code. So if it's compiled into the kerne= l with cam also compiled into the kernel, I know it works.

Also, the disk report needs full logs with and without th= e settings that have uncorrectable in them. I'd expect that a shorter t= imeout would lead to different behavior, but maybe that error syndrome isn&= #39;t one I've seen. It would also be helpful to know which of the time= s changes the behavior...

The offline marked partitions are o= n the same HD (the broken one). The
DISK-S649NL0T819360V device use as = log and cache in the second pool
causes the issue on 16-current.
On 16-current I get "uncorrectable parity/CRC error" messages on= boot
from the broken disk. I used this to get rid of those errors:
= ---snip---
# grep kern.cam /tmp/be_mount.MhLw/boot/loader.conf
kern.c= am.tur_timeout=3D"60"
kern.cam.inquiry_timeout=3D"60"= ;
kern.cam.modesense_timeout=3D"60"
---snip---

But t= he second pool ("space") fails to get imported. When I import it =
via "zpool import -m space" it shows me that the log and cach= e devices
(different partitions on the same hardware) are not available= .
This is the device in question as seen from 15-current:

In case you need some info from = the 15- or 16-current BE, which info do
you need?
