Issuing reboot over ssh causes the device to be lost to network but never actually reboots. Hench crashing

Call me a pedant, but when a device locks up it usually isn't described as "crashing" (a crash would suggest a process has quit unexpectedly - in the case of Kodi producing a crashlog, or if the kernel a backtrace).

I don't dispute you are experiencing a problem of some kind that isn't easy to reproduce, just asking that the problem is described accurately.

It's any of the episodes, it happens on all of them.

Are you able to identify the build when the problem started?
