cubox-i tvheadend kernel oops

[michalMember]

I am running geexbox on a Cubox-i4. I see periodic kernel oops’s. These are triggered sometimes by xbmc itself, but more often by tvheadend.

I am using a Hauppauge WinTv-HVR-950Q tv tuner stick (uses au0828 and au8522) modules.

While xbmc seems to actually stay functional, the tvtuner stick doesn’t work at all afterwards.

Looks like a memory leak. But I cannot tell from the log who is causing it (XBMC, tvheadend ot the hardware driver).
