[ivtv-users] PVR-500 has working video0, failing video1/2/3 (long)

[Trevor Boicey]

One line version:
- PVR-500 drivers work for both encoders in two cards using linux 
2.6.13/ivtv-0.4.1, in linux 2.6.32 only first encoder produces MPEG 
data, the other three produce... something else.

Short version:
- Attempted to upgrade an older mythbox (kernel 2.6.13/ivtv 
0.4.1/working for years) to current codebase, along with some hardware 
upgrades. Collapsing two mythboxen into one, so I have extra hardware.
- I have three PVR-500s, Revs D492, E587, E787. All working a week ago.
- Problem occurs with as little as one PVR-500 in PC, I have tried each 
of the three individually with same results.
- In new PC, using 2.6.32, video0 works perfectly. video1 seems to set 
up alright, and dmesg looks normal, no errors.
- When I do "cat /dev/v4l/video0 > foo.mpg" it produces a usable mpg
- When I do "cat /dev/v4l/video1 > foo.mpg" it produces many more bytes, 
and not an mpg.
- Same effect if I add another PVR-500, video2 and video3 also fail.
- However, if I reboot with kernel 2.6.13, and build ivtv-0.4.1, and 
install those modules, everything works fine.
- No module options, both kernels use the same /dev structure and same 
device nodes, and install the same firmware file.
- Seemingly identical conditions except kernel version and driver version.

Long data:

Here is the logs for 2.6.32, two cards installed. Only the first encoder 
of four works. (video0)

More debugging information:

Is this right? lspci shows the cards at 03:09 and 03:09, but v4l2-ctl 
shows them both as unit #1 and at 03:08:

Also notable, the pixel format for each tuner is listed differently, the 
working one is MPEG, the non-working one is HM12. Setting the 
pixelformat with v4l2-ctl doesn't seem to affect it, no error but it 
stays as HM12. I can change the resolution successfully though.

I hope something in there is useful.
