Hi! So, I have a PVR 500 that used to work wonderfully, but now constantly produces DMA timeouts. I'm running Debian Etch with the latest stock 2.6.18 kernel, and ivtv 0.10.6 compiled from source. I use mythtv 0.21.
Lately, (past several months... hard to determine exactly when) nearly every recording produces 0 byte files, and syslog is full of these messages: Jun 11 08:58:32 jumbo kernel: ivtv1: DMA TIMEOUT 00000001 0 Jun 11 08:58:36 jumbo kernel: ivtv0: DMA TIMEOUT 00000001 0 Jun 11 08:58:37 jumbo kernel: ivtv1: DMA TIMEOUT 00000001 0 Jun 11 08:58:41 jumbo kernel: ivtv0: DMA TIMEOUT 00000001 0 Jun 11 08:58:42 jumbo kernel: ivtv1: DMA TIMEOUT 00000001 0 I've tried cold-booting, I've tried changing the PCI latency (currently at 32). I've verified I have the latest firmware. (All suggestions from searches through mailing lists) Simply doing this: cat /dev/video0 > test.mpg produces a 0 byte file and causes the log messages, so mythtv is not likely to be responsible. Here are my startup messages: Jun 9 19:53:12 jumbo kernel: ivtv: ==================== START INIT IVTV ==================== Jun 9 19:53:12 jumbo kernel: ivtv: version 0.10.6 (tagged release) loading Jun 9 19:53:12 jumbo kernel: ivtv: Linux version: 2.6.18-6-k7 SMP mod_unload K7 REGPARM gcc-4.1 Jun 9 19:53:12 jumbo kernel: ivtv: In case of problems please include the debug info between Jun 9 19:53:12 jumbo kernel: ivtv: the START INIT IVTV and END INIT IVTV lines, along with Jun 9 19:53:12 jumbo kernel: ivtv: any module options, when mailing the ivtv-users mailinglist.
