saa7134-dvb not loaded automatically

[Matthew Wire]

saa7134-dvb module is not loaded automatically for KWorld dvb-220t card. Note, this is a hybrid analog/digital card. saa7134 is loaded automatically for the analog portion of this card.

lspci -v output for dvb card:

Please let me know if I can provide any further information.

More then just modules for your card don't get loaded.

NTSC/ATSC modules is are no loaded automatically at boot with my WinTV-D PCI card. I know for a fact the NTSC part of my card works under linux because I had KnoppMyth installed before Ubuntu and loaded it fine.

I can confirm that this bug is still present in the latest Feisty kernel. On boot the module will not be loaded until manually 'modprobe'd. After which dvb does work correctly.

[AndrewArchibald (andrew-archibald)]

Also attaching my 'lspci -v' output in case that helps. If I can help in any other way just let me know.

[AndrewArchibald (andrew-archibald)]

Poster on upstream mailing list suggests creating a file '/etc/modprobe.d/dvb' with the contents attached.

This works for me. Is there any chance we can have this fix or something like it merged in? With this the card seems to Just Work.

Reference: http://www.linuxtv.org/pipermail/linux-dvb/2007-March/016796.html

[MarkusRechberger (mrechberger)]

I committed a better fix for this issue a while ago, it's already live in the v4l-dvb repository on linuxtv.

http://lists-archives.org/video4linux/16410-v4l-saa7134-module.html

[AndrewArchibald (andrew-archibald)]

I can confirm that this issue is now fixed upstream as MarkusRechberger says. Installing the latest modules from the v4l-dvb repository works for me.

[Andrew Sayers (andrew-bugs-launchpad-net)]

I've not tried the latest DVB modules, but the workaround mentioned earlier didn't work for me.

People that have reached this page from Google might want to try the following workaround before they go installing packages from non-Ubuntu repositories:

In a terminal, do:

cat > /tmp/dvb << END && sudo mv /tmp/dvb /etc/modprobe.d/dvb
#
# Load the saa7134-dvb driver when the saa7134 module gets loaded
#

install saa7134 /sbin/modprobe --ignore-install saa7134 ; { sleep 1 ; /sbin/modprobe saa7134-dvb ; } &
END

Then restart your computer. Remember to type END then press <enter>.

If this doesn't work for you, you should delete the file '/etc/modprobe.d/dvb' by typing the following into a terminal:

sudo rm /etc/modprobe.d/dvb

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

[Leann Ogasawara (leannogasawara)]

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

The DVB drivers load properly for me when cold-booting into an Alpha 5 rescue CD. The driver won't load at all after a restart, although I think that's a hardware issue with my machine, so I consider this bug fixed.

[troosh (trush)]

Newer 2.6.27 kernel is not resolve this bug.
