cx23885 oops during loading, WinTV-HVR-1850 card

cx23885 oops during loading, WinTV-HVR-1850 card

[Ralph Siemsen]

I picked up an HVR-1800 but the box contained an 1850.  Encouraged by
other reports of success on this list, I plunged ahead and tried it.
However, the driver oopses during loading, and oddly, after that point
my terminal loses job control (can't ^C or ^Z anymore... weird.)

System is running Fedora 12 with kernel 2.6.31.9-174.fc12.i686.PAE.
Stock driver in fedora works, but does not reckognize the 1850.
Motherboard is an Intel DG45FC with a Core 2 Duo.

So I compiled v4l-dvb from HG against the fedora headers and loaded the
new modules, that's when the opps happens.  Details below.

I tried replacing only the cx23885.ko driver, as well as installing all
of the v4l-dvb drivers -- behaviour seemed to be the same.  With all
drivers installed, system bootup does not complete, udev hangs, but I
see the same kernel oops from cx23885.

Question: should I be trying this against vanilla kernel?  Or should I
try investigating the oops to see if I can figure out what's wrong?
Any other debug/diagnostics I can provide?

Thanks!
-Ralph

Solved this part, the oops was caused by the missing sysfs NULL,
already reported at http://patchwork.kernel.org/patch/70126/

Now the driver loads, and I follow it up with "modprobe tuner".
Unfortunately, no luck yet using tvtime, it just reports:
videoinput: No inputs available on video4linux2 device '/dev/video0'.
But I suspect that is a different issue!

The cx23885 driver doesn't work with tvtime, due to bugs in the v4l
controls in the driver.  Michael Krufky has some patches but they need
some more work before they can go in the mainline.  Even if they were
committed though, there is currently no support for raw audio, so
tvtime would not be a good application to use for this device.

Thanks for the tip.  I've tried all the other clients I could get my
hands on, including xawtv, mplayer, and xine.  Unfortunately, I have
not managed to get a picture (or even an empty window) out of them.
Is there a way to get it working?

Mplayer plays local media files and DVDs happily, but when I
try to input from /dev/video, or use the tv:// args, it complains:
    v4l2: ioctl dequeue buffer failed: Input/output error, idx = 0
over and over again.  The other clients just hang or exit.

I'm not sure what to try next.  Here is a typical log, I have tried
many variations, but the end result is always the same.
