This bugreport is really telling: https://bugzilla.redhat.com/show_bug.cgi?id=1161491 Here is copy/paste what bug reporter has found out: I then freshly installed Fedora 20 and tested some kernels: 3.17.2-300.fc21 on updated F20 : doesn't work 3.17.0-1.vanilla.mainline.knurd.1.fc20.x86_64 : doesn't work 3.17.2-200.vanilla.stable.knurd.1.fc20.x86_64 : works I then tested vanilla kernels on a new F21 installation, with the following results: 3.17.1-302.fc21.x86_64 : doesn't work 3.17.2-300.fc21.x86_64 : doesn't work 3.17.0-1.vanilla.mainline.knurd.1.fc21.x86_64 : doesn't work 3.17.2-300.vanilla.stable.knurd.1.fc21.x86_64 : doesn't work I don't exactly know what to do with this information, especially since 3.17.1 and 3.17.2-300 don't seem to work, but 3.17.2-200.vanilla.stable does. -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
