hdhomerun ERROR: lock no longer held

I'm running v29-rc1-4-g696806310a
Ubuntu 17.10
hdhomerun HDHR3-US Firmware: 20170930
Mythtv works for a while, several hours usually, and then it stops recording and my logs fill up with this. I've been rebooting my computer to fix it. Any suggestions?
Code: Select all

I see you are using a pre-release build of v29. I would recommend getting the latest from fixes/29. I don't know if that will fix the error.
Are there any other errors in the log before these messages start, that may indicate the cause?

If I run
Code: Select all
$ apt-cache policy mythtv
mythtv:

Is something wonky there?
I can't find anything else in the logs. Quite a few of these.

Another thing I can suggest is periodically reboot the HDHomerun Prime. I have a ceton eth 6. It has a memory leak that causes a failure after about 6 weeks. I reboot it once a week with a script to avoid that. There may be some command in the hdhomrun utility program to reboot it.
Otherwise I suggest open a ticket so that somebody may look at it.

This is my HDHR info from its web page:
Code: Select all
HDHomeRun Prime Tuner
Model: HDHR3-CC
Firmware: 20130328
I don't do routine boots, but it's a good test to see if it helps your case.
To be clear @alforddm, are there any other users of the HDHR on your
network? Tablets/Kodi/WMC/tvtime...
Can't speak to the policy, but maybe look for other instances of the backend:
Code: Select all
sudo locate -b "\mythbackend.real" "\mythbackend"

There "shouldn't" be. I did a trial run of recording via plex but then went back to using mythtv and removed the tuner from the plex ui. I wondered if somehow plex wasn't still grabbing the turners so I completely removed it and after I restarted the computer, the error hasn't reoccurred. It's only been 24 hrs so I don't know if that actually fixed the problem, or if just hasn't reoccurred. I was pleasantly surprised this morning to find it still working.

I've just got a new HDHOMERUN (a second one) as I think (or thought) my Nova-TD500 was faulty. The new homerun is not working from MythTv front end with the same error as above, the very old homerun (with the same firmware) is working fine. From the backend the new one scans channels ok in setup but if you got into the front end turner states window it shows the device has an error
