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)

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

Config is in attach.
