Turns out this is a kernel panic described here: https://www.mail-archive.com/ubuntu- b...@lists.ubuntu.com/msg5949850.html
to do with the Elantech driver. In that thread Chris Chiu states "It should be caused by the kbuild flag `-fcf-protection=none` and this will not be applied for the UBUNTU release image." I tried the kernel he compiled, presumably without that flag: https://people.canonical.com/~mschiu77/lp1941773/I/ and it works. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1945531 Title: screen freezes at boot Status in Ubuntu MATE: New Status in linux package in Ubuntu: Incomplete Bug description: On do-release-upgrade to Impish with the 5.13 kernel the boot messages stop scrolling at: fb0: switching to amdgpudrmfb from EFI VGA The system may be continuing to boot but the screen stops updating.
