Post subject:  ivtv module not loading after 1st reboot of R4V5 autoinstall
I have a system (2.8GHz P4) with two Hauppage 250 cards.
I did the autoinstall and configure the system on the initial boot
(no XvMC, but ir remote support). Everything looks great,
I can do PIP with both tuners, etc.

Then I exit MythFrontEnd and cleanly shutdown and restart
the machine. Once X11/gdm are back up the setup window
shows up again instead going directly to the MythFrontEnd. The
ivtv module isn't being loaded. I get all sorts of errors about /dev/video0
not being available, etc.

If I "modprobe ivtv", it loads the module, but Myth won't display
any output. (Perhaps I'm missing some config options?, etc.)

Any idea why modules aren't being loaded?
(Is the autoloader missing something?)

What's the easiest way to get the system loading the correct modules
with the correct config? (Not afraid to re-install, nothing to lose. :) )

Thanks,

Enone

Post subject:  Followup...
Reading through this related post:
http://mysettopbox.tv/phpBB2/viewtopic.php?t=2295

I see that I can cause ivtv modules to load at boot time by placing 'ivtv' in /etc/modules.

So the modules are now loading, but the options, etc. don't seem to be correct as the myth gets IO errors trying to read from /dev/video, etc.

Looking at the above post they mention that /etc/mythtv/modules
contains module specific options.

Mine currently looks like:

alias char-major-81 videodev
alias char-major-61 lirc_i2c
options ivtv debug=1
options tuner type=2
options msp3400 once=1 simple=1
add below ivtv msp3400 saa7115 tuner
add above ivtv lirc_dev lirc_i2c

It looks like I'm suppose to be able to add a "card = XX type=39" to the ivtv line, where XX is gotten from doing a lspci -V.

However, I don't see any "card" line when I do this:


01:04.0 Multimedia video controller: Internext Compression Inc: Unknown device 0016 (rev 01)
Subsystem: Hauppauge computer works Inc.: Unknown device 4009
Flags: bus master, medium devsel, latency 64, IRQ 11
Memory at f8000000 (32-bit, prefetchable) [size=64M]
Capabilities: [44] Power Management version 2

01:06.0 Multimedia video controller: Internext Compression Inc: Unknown device 0016 (rev 01)
Subsystem: Hauppauge computer works Inc.: Unknown device 4009
Flags: bus master, medium devsel, latency 64, IRQ 9
Memory at f4000000 (32-bit, prefetchable) [size=64M]
Capabilities: [44] Power Management version 2


I've tried card=85, card=83 and card=82 without luck.

It's so odd that the initial boot of Knoppix works great and then the first
reboot seems to loose all of its config. :(

Any suggestions appreciated,

Thanks,

Enone

I don't think the ivtv drivers support a card= option that is the bttv drivers. I think the ivtv drivers only support type= or something like that. You haven't installed a 2.6 kernel by chance have you?

Post subject:  Narrowed down the problem to myth install script...
I got the card=xxx for ivtv drivers from this post, although
re-reading it, it may just be a snippet from something at myth.org.

The kernel is 2.4
Code:
root@narcism:~ # uname -a
Linux narcism 2.4.25-chw #1 Sat Apr 10 15:46:31 PDT 2004 i686 GNU/Linux

I've tried setting the tuner type to 39, which doesn't change things. :(

Interestingly enough I have narrowed down the problem a bit.
It's not the reboot, it's the inital mythtv install script.

Initial boot after install:
Code:
cat /dev/video0 > /tmp/test
is ok

Go through mythtv install script and just setup networking and reboot:
Code:
 cat /dev/video0 > /tmp/test
is ok

Install myth pkgs by hand
Code:
install-i686-l

and then reboot
Code:
 cat /dev/video0 > /tmp/test
is ok

Following the mythtv install script between installing packages but before running through mythtv-setup (where mythtv install script creates directories, links dvd-rom, starts and stops myth/mysql, etc.), and reboot:
Code:
root@narcism:~ # cat /dev/video0 > /tmp/test
cat: /dev/video0: No such device

Does anyone know the name of this initial install script?
I might want to run through it by hand and see if anything looks suspicious. Any other suggestions welcome.

Thanks,

Enone

The thread you are reading about applies only to the new ivtv cvs builds.. .1.9 that comes with knoppmyth by default does not use the card= stuff in that thread. you need to upgrade IVTV if you want to use those options.. If it worked at first, it probley means you dont have one of the new cards.. Newer cards (i have two now) need the new ivtv drivers.

Post subject:  Probably older 250 cards...
I suspect I do in fact have the older cards. They are several years old:

Code:
01:04.0 Multimedia video controller: Internext Compression Inc: Unknown device 0016 (rev 01)
        Subsystem: Hauppauge computer works Inc.: Unknown device 4009
        Flags: bus master, medium devsel, latency 64, IRQ 11
        Memory at f8000000 (32-bit, prefetchable) [size=64M]
        Capabilities: [44] Power Management version 2

01:06.0 Multimedia video controller: Internext Compression Inc: Unknown device 0016 (rev 01)
        Subsystem: Hauppauge computer works Inc.: Unknown device 4009
        Flags: bus master, medium devsel, latency 64, IRQ 9
        Memory at f4000000 (32-bit, prefetchable) [size=64M]
        Capabilities: [44] Power Management version 2


Does this mean that the myth autoinstall/install script work with the old cards? Is there a separate process for getting the old 250 cards working?

Thanks,
