Is this a regression? i.e. Did you have reboot working fine before installing some updates? (In reply to comment #0) > pivot failed: invalid argument There may be something wrong with your initramfs. Try regenerating it with "dracut -f". > Restarting system This message is printed by the kernel. Reassigning. Does a forced reboot work?: sync && reboot -f Would changing the kernel's reboot method with the "reboot=..." parameter help?
