[Touch-packages] [Bug 1979066] Re: BUG: kernel NULL pointer dereference, address: 0000000000000300
We should probably ignore "Corrected error" because those are just hardware errors and whether they're related to the kernel crash or not, the kernel still should not crash. Please try a newer kernel version such as: https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.18.4/amd64/ or just install Ubuntu 22.04 if you can. ** Package changed: xorg (Ubuntu) => linux-hwe-5.13 (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1979066 Title: BUG: kernel NULL pointer dereference, address: 0300 Status in linux-hwe-5.13 package in Ubuntu: New Bug description: Recently I experienced the issue that after dis- and reconnecting my monitor (Philips 346B1C) with USB-Hub, my laptop (Lenovo E480) did not accept any inputs (mouse or keyboard, neither), while the display looked OK.
