NULL dereference on start-up, leading to unusable system. Used "git clone --depth=1 --single-branch --branch next-20191115 https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git" Where I am, I cannot use serial console to save the stack trace. I will attach a photo of the screen. The top few functions are: kernfs_find_and_get_ns sysfs_remove_group netdev_queue_update_kobjects netdev_unregister_kobject This leads me to believe that it is part of networking. I will do a bisect if I have to, but given how time consuming they are on a quad-core machine, I hope somebody else with a 32-core Threadripper can step up to the task. -- You are receiving this mail because: You are the assignee for the bug.
