I did not make any kind of configuration change or install any package. So there we go. I left the bug open and there are some better 'strace's in the bug, but I suppose unless anyone else sees this soon we can close it.

The kernel module is included in the rawhide (and only rawhide) kernels, however it is not enabled by default. A user needs to explicitly specify kdbus=1 on their kernel cmdline to enable kdbus. The reason being that we do not want to have rawhide default to something that is not going to ship in the next release, and we are not going to include the kdbus code in the kernel on a stable release until it is merged upstream. josh -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct

As I understand it, the plan was to switch it on in rawhide, but I'm not sure what happens if you just upgrade like that. You should see kdbus in /proc/cmdline - and no system dbus process. I think it'd be an interesting exercise to turn it off if it's on, and on if it it's off. :) -- Matthew Miller Fedora Project Leader -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct

OK so this is like throwing spaghetti, but maybe valgrind, something like: valgrind --leak-check=full --show-leak-kinds=all --track-origins=yes -v sudo bash Of course that'll almost certainly lead you down a debug package installation rabbit hole for a period of time. -- Chris Murphy -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
