Hi, Each time I turn off Fedora 24, I get the following message about 50 times printed in the console: Kernel not configured for semaphores (System V IPC). Not using udev synchronisation code. device-mapper: remove ioctl on fedora_alpha-root failed: Device or resource busy Command failed What does that mean? Thanks, Frédéric _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
