I think it's actually needed to properly log the errors coming from the kernel. However, I see from the docs https://github.com/andikleen/mcelog that it has a "trigger" mode, where the kernel calls it on an error. Upstream doesn't recommend it because it doesn't enable some fancier features, but maybe that would be a better default for desktop > Esp. given that ECC RAM is something which most Fedora Workstation users won't > have, so having this included / enabled by default feels wrong IMHO. It's my understanding that it also handles other CPU errors and -- probably very relevant to many Fedora Workstation users -- thermal CPU throttling events. -- Matthew Miller <mat...@fedoraproject.org> Fedora Project Leader _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org 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/devel@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
