bug#44927: Guix reboot stops with some errors

Hello!
I have a trouble that I cannot solve and did not have such before.
When I reboot or power off my pc the process of shutdown stops with lines of 'call trace' (in attach).
It happened today after hundreds of tries of update with network errors (from guix server as I think)
https://lists.gnu.org/archive/html/help-guix/2020-11/msg00220.html

I just added another disk to my system, it works fine.
But something happened.
Please where to dig?

Config is in attach.

I have deleted lines with disks in config and reconfigured but the error remains.

I switched to generation (system and packages by root) but an issue remains.

In Attach entire screen with trace.

What is that?

Just a guess, from my experience with device busy messages:

Is there a process which has a current working directory on the device when you shut down?

(E.g., I think it could happen if you had cd'd there to look around, and forgotten to cd back out first.
Or perhaps there is a bug doing something similar?)

Since you’re on an EFI machine, could it have to do with
<https://issues.guix.gnu.org/44956>?

If that is the case, it would seem that the solution is to pull and
reconfigure to a kernel >= 5.9.12 (the default in current ‘master’).

HTH,
