Yes I think that's it, since the machine was a server that hadn't done
an NTP sync before.

Perhaps we should consider using Fibers 1.1 for all architectures? This
problem occurred on a x86-64 machine. This issue reverted Fibers 1.3
just for ARM:
https://issues.guix.gnu.org/64966#6

Based on the Github discussion, it seems this bug isn't a priority for
the Fibers maintainers, and it has been an outstanding (and seemingly
common) issue for almost a year now.

Could it be that your system clock changed drastically, for instance in
response to ntpd synchronization?  There=E2=80=99s a bug when that happens:

On a new Guix 1.4.0 install, I logged in and ran `herd status` to check
if sshd was running. However, the command blocked indefinitely with no
output. When I cancelled that and tried to shut the machine down with
`halt`, it also blocked and did nothing. The system was not being
reconfigured at the time.
