That would suggest to me that determining the cause of the slowdown is most important. When the slowdown happens, can you switch to another VT (ctrl-alt-F2) or ssh in from elsewhere and see if there is any unusual CPU or I/O activity? It sounds as if this issue happens for you frequently? And, are you still on the kernel shown in the BZ? There have been updates to the kernel since that time. -- The key to getting good answers is to ask good questions. _______________________________________________ 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
