I have a stream of messages on the console, as follows:
Message from syslogd@Bree at Sep 23 03:56:24 ... kernel:watchdog: BUG: soft lockup - CPU#0 stuck for 4802s! [kworker/0:0:323591]
This is F34, fully updated. I've not seen this before.
Any ideas?

Do you collect sysstat information? Any high CPU usage during the same time?
Others have reported these errors when systems have over heated.

The system was idle overnight, so shouldn't have been overheating. However on checking the journal I see a whole stream of messages from upowerd about a USB over-current condition, which seem to be close in time to the lockup messages. I also noticed that my USB-connected printer wasn't responding. I've now connected the printer wirelessly and it's working fine. I have a USB-3 multiport hub, so that may the the root cause.
I've not explicitly enabled sysstat collection (how do I do that?)

Done, though I thought iostat etc. were already working even without installing the sysstat package.

iostat is only real time view while you are running it.
sysstat collects long term data and keeps for weeks(cpu, disk, network, and a lot of other things). I generally turn systat/sar down to 1 minute so I have more detailed data. It is useful when something odd happens to see what the system looked like.
