Once Pi is fully booted up it appears to be stable for long periods and I can use both PVR via live TV option in GUI including EPG information etc.
(been using/testing like this for a while with nightly milhouse builds) .

I don't believe two PVRs is a supported configuration. Can you disable one and confirm if hang still occurs?

Just updated to #0705 and with only one PVR enabled, had following single kodi crash during 1st boot-up

Kodi Crashlog and then kodi.log after clean boot into kodi after crash.
