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
