The chip didn't lock to the input signal.
What kind of input are you feeding into the card?
Ah, for most of the testing I've done during the week I haven't had
anything plugged in. Though (obviously) I have tried with some cameras
plugged in. I have 3 "bullet" cams and one mini security camera. All
just standard wired video outputs, PAL, colour. They work fine on the
IVC capture card I have.
I've rerun the test with irq_debug=1 and the /var/log/messages output is
here: http://pastebin.com/AJSLBhtY I don't think it looks any better
(/different).
Can you run the attached program while xawtv is running?
It will dump most of the registers of the bt8xx video function.
Sure, output below. It didn't print out anything until I ran it as root
(failed on fd = open(path, O_RDWR|O_SYNC);). The output remains pretty
much the same over multiple runs except these two values:
0E8 FCAP flips between a few values
100 INT_STAT changes from 0A00000C to 0B00000C and back.
Full output with xawtv running, bttv module loaded with no params.
