Greetings, I'm working on getting the last few issues cleaned up with a MythTV setup. One of the issues I have, is that whenever I access the first tuner on my PVR-500, I get a series of DMA warnings/errors:
May 1 00:06:08 mythtvserver1 kernel: ivtv1 warning: ENC DMA ERROR b May 1 00:06:08 mythtvserver1 kernel: ivtv1 warning: encoder MPEG: offset 0 -> 128 May 1 00:06:08 mythtvserver1 kernel: ivtv1 warning: encoder MPEG: offset 128 -> 104 May 1 00:06:10 mythtvserver1 kernel: ivtv1 warning: ENC DMA ERROR b May 1 00:06:10 mythtvserver1 kernel: ivtv1 warning: encoder MPEG: offset 104 -> 128 May 1 00:06:10 mythtvserver1 kernel: ivtv1 warning: encoder MPEG: offset 128 -> 36 May 1 00:06:15 mythtvserver1 kernel: ivtv1 warning: ENC DMA ERROR b May 1 00:06:15 mythtvserver1 kernel: ivtv1 warning: encoder MPEG: offset 36 -> 128 May 1 00:06:15 mythtvserver1 kernel: ivtv1 warning: encoder MPEG: offset 128 -> 0 May 1 00:06:22 mythtvserver1 kernel: ivtv1 warning: ENC DMA ERROR b May 1 00:06:22 mythtvserver1 kernel: ivtv1 warning: encoder MPEG: offset 0 -> 128 May 1 00:06:22 mythtvserver1 kernel: ivtv1: DMA TIMEOUT 00000001 0 Now, the above seems to only to occur on ivtv1 (the first tuner of the pvr-500). I also have a pvr-150 installed, which consumes ivtv0 (video0). With video0 in use (recording), if I cat from video1 (first tuner), I almost immediately get the above. If I then turn around and cat from video2 (second tuner), it works fine with no errors. I notice that all three ivtv devices are currently on the same interrupt. Is this a cause for concern? Would moving the cards impact this (the problem, not the interrupts)? Changing the interrupts? Indications of a bad board? All of the above? None of the above?
