TrueNAS-13.0-U1 kernel panic when moving a disk to another iron server slot

[volff]

Hello Guru.

We've run into strange TrueNAS 13 behavior. We've installed the operating system. We have made the initial configuration.
The action of ejecting the SAS disk and moving it to another slot caused a kernel panic (dump attached).
Our hardware:
HP Apollo 4200 54 SFF (ProLiant XL420 Gen9)/RAM 1tb/22-disk's SATA 3.84tb/ 2-disk's sas 3.84tb/ 2-disk's sata 250gb
Controller b140 for booting the operating system, mode AHСI, 2 disk's ssd sata 240Gb, disk position number on hardware system: 53.54
Controltr Smart Array P840ar, mode HBA, for DATA array, disk position number on hardware system: 1-52.
22 SATA drives and 2 SAS drives are connected to the Smart Array P840ar controller.
When we moved 8 disks from bucket 2 to bucket 1, this caused a kernel panic.
We reproduced this situation with SAS disks. This can be seen in the text dump.
- We removed the SAS drive from slot 8 and moved it to slot 9. the system could not determine it, but continued to work.
- We removed the SAS drive from slot 7 and moved it to slot 10. the system went into kernel panic mode.

After a reboot, the system works fine with disks 9 and 10.

Help deal with the problem.

When you say "Mode HBA", what do you mean by that?

I suppose you already know or saw this: https://www.truenas.com/community/t...s-and-why-cant-i-use-a-raid-controller.81931/

Perhaps the controller doesn't properly support hot-plugging in that mode?
