I've been seeing a kernel panic on shutdown/reboot with Fedora 23. While it occurs after disks are finalized, it may prevent restarts from occurring on reboot. Any ideas how to address this? Hardware is Beagleboard XM rev B. Fedora 23 has been quite stable otherwise. Kernel: 4.2.6-301.fc23.armv7hl Partial root console reboot log: [ OK ] Reached target Shutdown.
