I need the logging during the 10 seconds leading up to HV> the first DMA TIMEOUT. I tried recording a bunch of stuff yesterday but failed to reproduce a TIMEOUT from it (arg). I vaguely recall someone else having a similar issue: reproducing it with debugging on seemed to be a problem. I did get one hard freeze but I'm not sure it was related to ivtv. Nor was it me that reset the box (it was my wife) so I'm not sure of the conditions at the time. Just in case, the following few lines occurred right before the freeze: Dec 4 18:03:13 dawn kernel: ivtv0 dma: start DMA for encoder MPEG Dec 4 18:03:13 dawn kernel: ivtv0 dma: include DMA for encoder MPEG Dec 4 18:03:13 dawn kernel: ivtv0 irq: ENC DMA COMPLETE 3 0 (0) Dec 4 18:03:13 dawn kernel: ivtv0 irq: ENC DMA COMPLETE 3 0 (0) Dec 4 18:03:13 dawn kernel: ivtv0 dma: DMA encoder MPEG completed (164ec0) Dec 4 18:03:13 dawn kernel: ivtv0 dma: PIO encoder VBI completed (0) Dec 4 18:03:13 dawn kernel: ivtv0 irq: ENC START VBI CAP Dec 4 18:03:13 dawn kernel: ivtv0 dma: PIO encoder VBI: 0x00001d40 bytes at 0x0 030a780 Dec 4 18:03:13 dawn kernel: ivtv0 irq: ENC START VBI CAP Dec 4 18:03:13 dawn kernel: ivtv0 dma: PIO encoder VBI: 0x00001d40 bytes at 0x0 02fea10 Dec 4 18:03:13 dawn kernel: ivtv0 irq: ENC START CAP 0: 00169ec0 00004000 Dec 4 18:03:13 dawn kernel: ivtv0 dma: DMA encoder MPEG: 0x00004000 bytes at 0x 00169ec0 Dec 4 18:03:13 dawn kernel: ivtv0 dma: start DMA for encoder MPEG Dec 4 18:03:13 dawn kernel: ivtv0 dma: include DMA for encoder MPEG Dec 4 18:03:13 dawn kernel: ivtv0 irq: ENC DMA COMPLETE 3 0 (0) Dec 4 18:03:13 dawn last message repeated 2 times Dec 4 18:03:13 dawn kernel: ivtv0 dma: DMA encoder MPEG completed (169ec0) Dec 4 18:03:13 dawn kernel: ivtv0 dma: PIO encoder VBI completed (0) Dec 4 18:03:13 dawn kernel: ivtv0 irq: ENC START CAP 0: 0016dec0 00008000 Dec 4 18:03:13 dawn kernel: ivtv0 dma: DMA encoder MPEG: 0x00008000 bytes at 0x 0016dec0 Dec 4 18:03:13 dawn kernel: ivtv0 dma: start DMA for encoder MPEG Dec 4 18:03:13 dawn kernel: ivtv0 irq: ENC DMA COMPLETE 3 0 (0) Dec 4 18:03:13 dawn kernel: ivtv0 dma: DMA encoder MPEG completed (16dec0) Dec 4 18:03:13 dawn kernel: ivtv0 irq: ENC START VBI CAP Dec 4 18:03:13 dawn kernel: ivtv0 dma: PIO encoder VBI: 0x00001d40 bytes at 0x0 0300520 (after that last line was a line of NULLs) -- "In the bathtub of history the truth is harder to hold than the soap, and much more difficult to find." -- Terry Pratchett _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
