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?) poc _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
