I sent this a few days ago, but it looks like I hadn't been
fully subscribed to the list at the time and the moderator
needed to approve it.
I was having ivtvX: DMA TIMEOUT 00000001 errors, so I updated to
0.10.6
After 1 day, 15 hours uptime, I got the same errors again. Many
previous recordings went well. These errors always occur during
a recording. When they happen, the ivtv device in question
becomes completely unusable.
This is a supplied Debian Etch kernel. Athlon 3500+ CPU, 1GB RAM,
a dedicated MythTV box. NVidia 5200, VIA K8T800Pro chipset.
I have options ivtv enc_mpg_buffers=16 enc_vbi_buffers=8 set in
modprobe.conf.
For the nonce, I've moved back to 0.10.1, where I get these
triplets:
ivtv0 warning: ENC DMA ERROR b
ivtv0 warning: encoder MPEG: offset 24 -> 128
ivtv0 warning: encoder MPEG: offset 128 -> 0
but the device remains usable, dropping a frame or two.
Diagnostics follow.
