Hi Scott, ----- Original Message ----- > 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.

Seems to affect the Panda and Beagle* on 4.2, but appears to be resolved in 4.3 (and 4.4) which should make its way to F23 soon. If you'd like to try it out, you can download from koji[1], let us know how it goes.
