Hey all, This is going to sound like a bit of a silly question. Has anyone tried the current v4l-dvb tip with a device that has IR support? I had been working on separate branches for the last few weeks, and finally updated to the tip. I'm seeing the exact same OOPS condition for both my em28xx and cx88 based device. Did someone break the IR core? This occurs 100% of the time in my environment when loading either cx88 or em28xx based devices that have IR support (a stock Ubuntu 9.10 build (2.6.31-17-generic) with the current v4l-dvb tip as of tonight.
