I don't know what's causing this. Been using the same tuner cards for years and other than this filling up the syslog file, the system seems to still work ok. I've got 3 fusion hdtv7 dual express cards containing 2 atsc tuners each. I don't know what's causing this, but it started sometime after switching to mythbuntu 14.04 a year or so ago. Anyone else seen this in their syslog file or have any idea who I should report this to?
Well, it's not a real signal strength issue. It's a known fact that the cards I use have never handled the reporting of the signal strength properly in mythtv. I don't recall if the problem was in the cards, mythtv, the drivers, or what, but it's never been an issue before in the 6 so years I've been using them. However, disabling logging as has done away with many problems I was having with frame buffer timeouts, and even pauses in playback on other frontends, which I never had on previous mythtv versions.

Yeah, I know it's not a real fix, but it let's my system function normally now. I don't know where the real problem is, but the logging of the problem causes so much disk activity on the backend, which causes frame buffer timeouts and pauses while watching recorded programs on any of my frontends. The error gets logged to the kernel log, syslog, mythtv backend logs, and maybe others. I know there's a way to filter them out in rsyslog.conf, but it's easier fro me to just disable logging than to try and figure it out. And fixing drivers, if that's where the problem is, is way beyond me. You can see the errors in my first post. If you know who can fix them, I'll be glad to give them the the logs. My tuner cards are Fusion HDTV7 Dual Express cards. Dual tuners. pcie format. I never saw all these errors until recently when I switched the backend to Mythbuntu 14.04 LTS from Manndriva 2010.2 if that matters. This is the first related post. viewtopic.php?f=36&t=737

All set for on demand in mythtv-setup.

I talked to Devin Heitmueller on IRC and he suggested you should try adding the no_poweroff=1 module option to prevent the module sending the card to sleep which will cause the firmware to reload the next time the card is used. So you would do something like add a file called /etc/modprobe.d/xc5000.conf with the content: options xc5000 no_poweroff=1. Then reboot so the new module option will be used.
You could also try telling Myth not to use the cards on demand unless you need to do that for some reason. That way Myth will keep the dvb frontends open and should prevent them sleeping which will cause the firmware to be reloaded when they are used.
Ok, I disabled on demand (and I can live with that) for all tuners and that got rid of the constant firmware uploading. Now how do I get rid of these that continue to fill the mythbackend.log and syslog?

As another workaround, I just filtered them out in rsyslog.conf file.
