Other kernels work. Do newer kernels work? Any chance you can run 'git bisect' to find the offending kernel patch? 4.19 is really old, is this a stable-update-issue, or a "something changed since 4.19 was released" type of issue? > Systemd issue is this one: https://github.com/systemd/systemd/issues/19926 I'm running systemd 248.3 just fine here on 5.13-rc6, so this seems odd... thanks, greg k-h
