Recently, two odd things began to happen related to my pvr350. The box is a p4 1.8. Here are the modprobe.conf lines relating to ivtv:
alias char-major-81 videodev alias char-major-81-0 ivtv alias char-major-61 lirc_i2c I also have a line setting some ivtv module options but tried removing it for a while and both problems still occured, so I won't incude it here. Here is my "dmesg|grep ivtv" for reference: (consider the last line to be repeated up to a few hundred times) Aug 16 05:10:32 localhost kernel: ivtv: ==================== START INIT IVTV ==================== Aug 16 05:10:32 localhost kernel: ivtv: version 0.3.7 (c) loading Aug 16 05:10:32 localhost kernel: ivtv: Linux version: 2.6.12-1.1372_FC3 686 REGPARM 4KSTACKS gcc-3.4 Aug 16 05:10:32 localhost kernel: ivtv: In case of problems please include the debug info Aug 16 05:10:32 localhost kernel: ivtv: between the START INIT IVTV and END INIT IVTV lines when Aug 16 05:10:32 localhost kernel: ivtv: mailing the ivtv-devel mailinglist.

I've begun to get "IRQ: IVTV_IRQ_DEC_DMA_ERR" messages on boot as seen above in my dmesg. I'm not sure at what version this problem presented itself, I believe it was after 7b but I just don't remember. They always start immediately after "Tried to open YUV output device but need to send data to mpeg decoder before it can be used" and repeat (sometimes a few or a few hundred times, not sure if this is related to setting changes or not) for less than a second. I occasionally will get these at other times, but didn't used to get a whole lot of then at boot. 2. About five times in the last week, the TV has seemed to nearly lose the signal from the pvr-350. I belive this problem manifested after 7c, but it may have been between 7b and 7c. The signal goes black and white, gets vertically displaced and wrapped around, gets very ghosted, etc. All the things that seem to happen on a normal channel whent the TV is trying to lock in to the signal. After between 30 seconds and five minutes things go back to normal. Turning off the TV, using the mpeg2 decoder, changing channels.(meaning on the tv not the tv card) etc. all seem to have no effect. No log messages or changes in my activity seem to be related to this. ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf _______________________________________________ ivtv-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/ivtv-devel
