[ivtv-users] MPEGRec(/dev/video0) select timeout - ivtv driver has stopped responding, zero-byte recordings

[David Kramer]

Hi.  My MythTV box has been running for a long time without problems, 
but this is the second time this has happened in a few weeks.  Lost 
quite a bit of the Olympics.

The recordings will be fine, then they're zero-bytes.  I see this in 
mythbackend.log:

  *********************** WARNING ***********************
  ivtv drivers prior to 0.10.0 can cause lockups when
  reading VBI. Drivers between 0.10.5 and 1.0.3+ do not
  properly capture VBI data on PVR-250 and PVR-350 cards.

2008-08-17 19:00:13.430 MPEGRec(/dev/video0) Error: select timeout - 
ivtv driver has stopped responding
2008-08-17 19:00:18.964 MPEGRec(/dev/video0) Error: select timeout - 
ivtv driver has stopped responding
2008-08-17 19:00:24.498 MPEGRec(/dev/video0) Error: select timeout - 
ivtv driver has stopped responding
(I see the above line hundreds of times)

Rebooting fixes that, but that's not a good solution.

Googling around and looking at the archives of this list, I see mention 
of turning off DMA on ivtv.  I don't know how to do that, but this box 
doesn't do that much else and it's usually over 90% idle, so I don't 
know that it would do any good.

I've seen other posts with this error in conjunction with other errors, 
leading to other causes (like directory positions), but the only 
messages I see are the message about the ivtv driver version, and the 
MPEGRec error.

I find the ivtv drivers error curious, since I'm running ivtv 1.2.0.

Any ideas?

Thanks.
