Sounds like a firmware bug. I wonder if it's strictly USB related or if it's at all triggered by the isohybrid nature of our ISOs - maybe it's more or less likely to happen if the USB stick were created using livecd-iso-to-disk with '--format --efi' options and allow it to blow away the entire USB stick. -- Chris Murphy _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-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/devel@xxxxxxxxxxxxxxxxxxxxxxx
