It turns out my MythTV tuning was incorrect as some channels had changed frequency due to the analogue switch-off. The card would freeze up when tuning to one of these channels. For some reason, this would prevent any further tuning on it. So after MythTV tried to record from one of these channels, it would prevent anything from being recorded on any channel. I have retuned and I haven't experienced any more lock-ups since about 1 week. -- Alistair Buxton a.j.bux...@gmail.com -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Commenting those three lines makes the driver work again. Don't know
yet if it will keep working for longer than a couple of days.
I suspect it is tuner GPIO. It is not clear which GPIO pins are used for
tuner reset. I should find this out soon. Most likely MXL5005S tuner
reset have connected to different GPIO than MT2060 design I have.
Could you test commenting out only gpio change to see if it helps?
After a couple of days the card locked up again just like before. Are
there more gpio bits I need to comment? The LED GPIO is definitely
right. Also, is there a way to check the status of the GPIO from
userspace, without recompiling the module? Like maybe with i2c-dev or
something?

Re: RTL2831U driver updates
Hi again, i managed to merge the driver with a media_build snapshot by hand, and managed to get it loaded without errors. But now where I looked more closely to the files, I noticed something. The driver refered mentions RTL2832u and some following versions, but it _dont_ mention RTL2831u at all. Also the card I got contains the tuners mxl5005, mt2060 and qt1010, while this driver contains files for mxl5007 and mt2063. Teach me wrong, but it looks like the RTL2381u had been forgotten when this driver got made ;-) Greeting, Thomas Sascha Wüstemann wrote: Jan Hoogenraad wrote: Sascha: Thanks for the links Would you know how to contact poma ? http://www.spinics.net/lists/linux-media/msg24890.html I will be getting more info from Realtek soon.
