2 problems with HVR-1300

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello, 

I am not a developer - this is a support request about (probably) the cx88* driver - if I am mistaking, please can somebody point me toward the correct list ?

I have an Asus P5K MB, architecture x86_64, under Ubuntu 10.04, but I just tested my hardware with a Fedora 13 Live CD, I have the same problems; I bought some months ago an HVR-1300, in order to use the mpeg encoder on the board.

>From the moment I installed the card, I use to have two problems :
- the boot stalls often, at some moment around the local disk mount; and a simple Reset or Power off/Power on, often are not sufficient. Now it's getting pretty annoying, especially because it's a random issue, BUT a frequent one; it makes me think of a race condition into the new Upstart parallel structure for the services startup at boot. But with the HVR-1300 unplugged the boot performs correctly !

- I have a TV decoder shipped by my TV provider, so I don't change the channels on the HVR-1300 but on the decoder; thus I use to watch TV in this simple way :

mplayer -vc mpeg12 -nocache /dev/video2 (mplayer /dev/video2 works as well, but with some glitches)

BUT : just after booting, /dev/video2 does not output any TV image; so I found a workaround : I start :

xawtv  -c  /dev/video1

then stop it, and restart mplayer again : and THEN the TV image is pretty good.

I noticed these two problems with Ubuntu 10.04, AND a Fedora 13 Live CD (both for x86_64)

I installed Windows 7 in a small partition, and I had none of my problems with w7, after having installed the HVR-1300  driver for w7

Browsing the forums and mailing-lists, I found that my problem could be an interruption problem : actually, I noticed many such messages these days in the logs :

kernel: [   16.191887] IRQ 18/cx88[0]: IRQF_DISABLED is not guaranteed on shared IRQs

=> The  board is sharing interruptions with the usb controller :

I dumped my /proc/interrupts below.

I tried to plug the HVR-1300 into another PCI connecteor, unsuccessfully - just the IRQ changed from 18 to 17 ....

And I did not find many cx88* options I could tune.

Does anybody have a hint ?

Best regards
