I immediately thought missing firmware in kernel, my kernel builds firmware in it, so I upgraded my firmware to latest on git.kernel and made sure I had no warnings in dmesg about missing firmware. Still, I receive this NULL pointer in the IP. If I disable my netmount on boot, I can login, but can not bring up my interfaces, still get a RIP err in kernel logs and cpu load sky-rockets. I am willing to help and provide as much info as possible, thank you. -- You are receiving this mail because: You are the assignee for the bug.
