Hi Guix, I have a laptop that's a little stuck in the past… more accurately January of 2020 thanks to what I believe to be an empty CMOS battery. As of recently (maybe it dates back longer, but I first experienced it two weeks ago and just now got to debugging it a little), Shepherd gets stuck at 100% CPU usage "early" on first boot. I can prevent this issue by getting the system time "close enough" to the actual time before the NTP sync, but see the first sentence. Not having a network connection also works, but that's somewhat unpractical. Also, the high CPU usage still occurs if a sync is done later. I have yet to encounter the bug post hibernation, but I also wish not to. There doesn't appear to be anything particular interesting in the logs either.
Cheers
