Problem with auto-loading modules on boot (2.6.0, but not specific)

Emp202 · 12-31-2003, 05:35 AM

Hi folks,

I managed to compile Kernel 2.6.0 on Fedora Core 1 today and though most things run perfect i have still some small issues:

1. At boot it tries to load modules "mousedev", "keybdev" and "toshiba_acpi" which arent there. Everything runs fine without them, i'd just like turning off the attempt to load.

2. Sound works, but only if i manually insert modules. I read on ALSA (compiled 2.6.0 with ALSA and OSS emulation support) and edited my modules.conf and modprobe.conf (both are identical on my system since i dont know which one does what, enlightenment would be appreciated) to contain this:

Quote:

# ALSA portion
alias char-major-116* snd
alias snd-card-0 snd-emu10k1

# OSS/Free portion
alias char-major-14* soundcore
alias sound-slot-0 snd-card-0

# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

install snd-card-0 /sbin/modprobe --ignore-install snd-card-0 && { /usr/sbin/alsactl restore >/dev/null 2>&1 || :; }
remove snd-card-0 { /usr/sbin/alsactl store >/dev/null 2>&1 || :; }; /sbin/modprobe -r --ignore-remove

install sound-slot-0 /sbin/modprobe --ignore-install sound-slot-0 && { /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || :; }
remove sound-slot-0 { /bin/aumix-minimal -f /etc/.aumixrc -S >>/dev/null 2>&1 || :; }; /sbin/modprobe -r --ignore-remove

However, only soundcore seems to get loaded at startup.
I still manually need to insmod ac97_codec.ko, insmod sound.ko and insmod emu10k1/ emu10k1.ko from the /lib/modules/2.6.0/kernel/sound/oss dir to have sound working.
Of course, that isnt very satisfying.

I suppose both of the above problems can be solved by editing the files for modules being loaded at startup (i thought this was modprobe.conf, but this cant be cause there is f.e. no mousedev and keybdev in there), but which would those be and what should they contain? Any help is appreciated.

For the mousedev/keybdev, this has to do with the /etc/modprobe.conf.dist which trying load them during the bootup time. You can safely ignore the error message but if it annoys you, you can always remove the offending lines.

For the sound card, I do have problem with mine too .. I've added few lines of code into /etc/rc.d/rc.sysinit to load the soundcard and BTTV card..

And another annoying thing about 2.6.0, just discovered it today and was wondering before what went wrong when my system was totally locked up .. no idea if this is USB or bluetooth problem but when I accidently disconnected my bluetooth usb adapter, the system is totally locked up .. no way of reviving it, no way to ssh in .. total lock up ..

--
update: my bad .. those error messages can come from the /etc/modprobe.conf.dist but check out the /etc/rc.d/rc/sysinit in the USB section too .. you may want to comment those lines that trying to load the keyboard and mouse .. the Toshiba ACPI thingy comes from the one section above the USB section .. doing modprobe -k in the ACPI module directory .. just remove the offending module will silent it up

Anyway .. if you're loading with rhgb (graphical display), you won't see all those error messages anyway..

Hi wiraone,
Thx for the great support. The closer look at rc.sysinit did the job with the clean boot for me. No more nasty red "Failed" there now. I dislike rhgb because i like to see whats going on, and i dont like the big nvidia logo that pops up on every X start with installed nvidia drivers to show up twice when booting.

What i still didnt get right is automatically inserting the 3 modules i need for OSS support. (ac97_codec.ko, insmod sound.ko and insmod emu10k1/ emu10k1.ko) I tried to insmod them at the end of rc.sysinit but when it comes to this at boot time it says unresolved symbol for two of them and doesnt load them (probably because they depend on another module thats not loaded when boot reaches the end of rc.sysinit). Any good idea how i can insmod them at every startup? I wrote a small shell script to do this, only thing i would need is having that executed with root privileges every start..

I've the following lines added to my rc.sysinit for loading my sound card driver:

Code:

# Added to load sound module
if [ `uname -r` == "2.6.0-1.104" ]; then
  alias=`/sbin/modprobe -c | awk '/^alias sound-slot-0 / { print $3 }'`
  if [ -n "$alias" -a "$alias" != "off" ]; then
      action $"Loading sound module ($alias): " modprobe sound-slot-0
      action $"Loading BTTV module : " modprobe bttv
  fi
fi

The above, I checked my kernel release so that it won't try to load my sound card driver twice when I'm in kernel 2.4 .. make sure that you've the /etc/modprobe.conf configured correctly .. What sound card do you have? Soundblaster I guess? Try do a '$ modprobe snd-emu10k1 ' and see if it is working for you.

And, if ALSA driver doesn't work for you, you may want to try the old OSS driver instead.

BTW, to remove the Nvidia splash screen .. add this into your /etc/X11/XF86Config

Option "NoLogo" "1" #Turn off logo display
