laptop failing with latest kernel update

hello, I performed a normal update today after some time without updating, which I believed contained a kernel update (to 5.16.5-100.fc34.x86_64 I believe). After doing the update and rebooting my pc started behaving erratically. Bootup time was longer, then it sort of got stuck, then some problems were reported by the reporting app in Gnome. My computer was simply malfunctioning all over the place, sometimes freezing completely. Decided to boot to the previous kernel (5.15.16-100.fc34.x86_64) and my pc is back to normal. The Reporting app does not let me send a report saying "The backtrace does not contain enough meaningful function frames to be reported. It is annoying but it does not necessarily indicate a problem with your computer. ABRT will not allow you to create a report in a bug tracking system but you can contact kernel maintainers via e-mail." How should I report this issue in this case? How can I change the grub boot default for now to boot to the older kernel by default? or should I try reverting (removing updated kernel) to the older kernel altogether for now? thank you, Anil F
