There is no BIOS update for this board, time for new motherboard?

Edit: It was SAA7164 driver causing this, there is a fix on linuxtv.org.

Why replace your hardware over an internal warning? | drivers/media/v4l2-core/v4l2-ioctl.c: | /*
* Drivers MUST fill in device_caps, so check for this and
* warn if it was forgotten.
*/
WARN_ON(!(cap->capabilities & V4L2_CAP_DEVICE_CAPS) ||
!cap->device_caps); |
Switch to a fixed version of your v4l2 driver and you will be fine. |

| Many thanks. I believe the driver in question is one of those driving my media cards. Now I have to figure out which one. They all in kernel drivers. |
