You may be right, although one thing is puzzling but it could just be perfect timing pointing me in wrong direction ref gnome
Been using the laptop today for a fair few hours and it has not crashed once in Fedora, then i noticed im using Wifi and not the usb-c ethernet adaptor that i normally use on the sofa. SO im going to test that and see if it is actually that causing the issue.
Just seemed odd previously that on kde based with the ethernet it did not happen but then it could be a myriad of things i guess. I will post the output
