[mythtv] Master: scheduled recordings fail to start

[John Pilkington]

On Thursday 21 I installed a local build of

mythtv-31.Pre.101.g5439651a2b-100.el7.x86_64.rpm, upgrading from
mythtv-31.Pre.61.ga99d3e6d78-100.el7.x86_64.rpm

On Friday 22 I upgraded my kernel from 4.4.174.1.el7.elrepo.x86_64 to 
4.4.175.1

Later on Friday I found that scheduled recordings had not started. 
Attempts to restart any still being broadcast failed, but were still 
marked as 'will record'

'Previously recorded' showed them as 'missed', and also showed several 
recordings for Friday 1  *Mar* 2019 as 'missed'  I deleted the shows 
marked in red from that screen, after which current shows could be 
restarted from the EPG.  Scheduling still failed.

I have raised a flag at elrepo, because it looked as if reverting to 
4.4.174 had worked, but this morning scheduled shows were missing.

I have now downgraded to the previous ga99d3e build of Myth and at 
present it seems ok.

I see there have been more 'initialisation' commits since my problem 
build, and maybe they have fixed it.  I have  e83b364 (current head) on 
the fc28 box but have not yet done appropriate tests on that.
