I do see a few DMA ERRORS, not particularly showing any pattern ivtv2 warning: ENC DMA ERROR b (offset 00106ec0, xfer 1 of 2, retry 0) ivtv2 warning: ENC DMA ERROR b (offset 00154ec0, xfer 2 of 3, retry 0) ivtv1 warning: ENC DMA ERROR b (offset 0010fec0, xfer 2 of 3, retry 0) ivtv1 warning: encoder MPEG: offset 132 -> 128 ivtv1 warning: ENC DMA ERROR b (offset 00131ec0, xfer 1 of 1, retry 0) ivtv1 warning: ENC DMA ERROR b (offset 001046c0, xfer 1 of 1, retry 0) ivtv0 warning: ENC DMA ERROR b (offset 000fa6c0, xfer 1 of 1, retry 0) ivtv2 warning: ENC DMA ERROR b (offset 0015e6c0, xfer 1 of 1, retry 0) Previously from observation a DMA ERROR b meant there was corruption in the output stream, I haven't determined if it still does. I see the code retries the DMA transfer, but I'm not convinced this doesn't mean there isn't corruption in the stream. Does anyone know? The sort of error counts i'm seeing over 48 hours streaming on 7 cards is: dmesg -s 300000|grep 'DMA ERROR'|cut -d \( -f1|sort|uniq -c|sort -n 5 ivtv6 warning: ENC DMA ERROR b 7 ivtv4 warning: ENC DMA ERROR b 9 ivtv5 warning: ENC DMA ERROR b 20 ivtv2 warning: ENC DMA ERROR b 22 ivtv3 warning: ENC DMA ERROR b 23 ivtv1 warning: ENC DMA ERROR b 31 ivtv0 warning: ENC DMA ERROR b ivtv0123 are on one pci bus and 456 on another bus, which may explain the distribution of the errors.
