Changes in cam/nvme causes issues?

Hi Warner,

I try to update a 15-current (as of 2025-11-27-110715) to a recent 16 
(as of 2025-12-13-132815). It fails to import a pool due to a missing 
nvme. I also have a broken HD in this system... to be on the safe side I 
mention it.

This is from 15-current:

           diskid/DISK-S649NL0T819360Vp3    ONLINE       0     0     0
---snip---

The offline marked partitions are on 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.cam.tur_timeout="60"
kern.cam.inquiry_timeout="60"
kern.cam.modesense_timeout="60"
---snip---

But the second pool ("space") fails to get imported. When I import it 
via "zpool import -m space" it shows me that the log and cache devices 
(different partitions on the same hardware) are not available.
This is the device in question as seen from 15-current:
---snip---
nda0: <Samsung SSD 980 1TB 2B4QFXO7 S649NL0T819360V>
nda0: Serial Number S649NL0T819360V
[1] nda0: nvme version 1.4
nda0: 953869MB (1953525168 512 byte sectors)
[1] GEOM: new disk nda0
...
[1] pass6 at nvme0 bus 0 scbus6 target 0 lun 1
pass6: <Samsung SSD 980 1TB 2B4QFXO7 S649NL0T819360V>
pass6: Serial Number S649NL0T819360V
[1] pass6: nvme version 1.4
---snip---

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

Bye,
Alexander.
