I am currently using the openelec OS - intel x64 3.1.6 build (uses a 3.10 kernel) and I'm using a sony play tv usb dvb-t dual tuner along with 3 dvbsky s952 tuners. The sony tuner alway seems to crash after a few days and this is the dmesg output i noticed this morning when i noticed that tvheadend was frozen. I use suspend and resume so that the pc goes to sleep when idle. The items below (cx23885_wakeup: 9 buffers handled (should be 1)) are coming from the dvbksy tuners and seem to appear when the pc is suspended and resumed but i dont think that is related to the sony tuner issue. Anyways if anyone knows what the issue might be or knows if anything can be done to prevent this crashing it would be appreciated. This has been happening with openelec for as long as i can remember and is not something that just started happening with the 3.1.6 build. Full dmesg output here - sprunge dot us forwardslash FDRN and output when crash occurred below.
