Hello,
I have 2 different grafic cards in my pc.
I have difficulties in initializing the correct card.
Is there any possibility to control the sequence for loading of modules which are in the kernel?
The only Idea which I have (to be tested the next days oń the machine):
blacklist module1
blacklist module2
and in an init script:
modprobe module1
wait 2
modprobe module2
In that I would be sure module1 is loaded before module2. But I dont know how to be sure the initialized hardware will have the correct IRQ in use.
If any boot code, or any other method, could overtake the sequenced loading of modules, I would be happy to know it.

If you have kernel modules for the graphics devices then you blacklist or force which to load first. Read man page of 'modprobe.conf'.

If you have included them in kernel then perhaps it can be disabled by passing kernel parameters. Run modinfo on the required modules, it would give parameters. Apply that to kernel command line while booting.

I created
##########################################
# file /etc/modprobe.conf
# http://linux.die.net/man/5/modprobe.conf
# http://www.linuxquestions.org/questi...6/#post5331676
install radeon /sbin/modprobe snd_hda_intel; /sbin/modprobe --ignore-install radeon
# https://wiki.debian.org/KernelModuleBlacklisting
include /etc/modprobe.d

in order to make the "radeon" loading in ANY case before the snd_hda_intel.
Do you think it is fine?
Then I will test

Yes it's fine.

For the reason it did not worked (sometimes, it loaded snd_hda_intel before radeon !? it seems I wroongly interpreted the man modprobe.conf), I blacklisted snd_hda_intel in /etc/modprobe-d/alsa-base-blacklist.conf
and
changed the file
##########################################

install snd_hda_intel /sbin/modprobe radeon
# https://wiki.debian.org/KernelModuleBlacklisting
include /etc/modprobe.d

NOW
radeon is loaded automatically in my PC at each boot (good).
snd_hda_intel is NOT loaded at boot (good: due to blacklisting).

Questions:
1) if I correctly understood, a "modprobe snd_hda_intel" would now load radeon before snd_hda_intel (if radeon not existing)?
2) Where should I put the "modprobe snd_hda_intel" in my antix system? (debian wheezy derivat) for having snd_hda_intel loaded automatically at boot ?
