kernel nightmare!

norkers · 04-25-2005, 04:10 AM

Hi all,

I've been having some problems with my system since I upgraded from kernel 2.4.26 to 2.6.11.7. I'm running Slackware 10.1.

Since I compiled my new kernel, the following problems are occuring...

* No sound! - Tried alsoconf, it just says it can't find any sound cards. Gnome can't find any sound devices. I think it's something I've done with the kernel settings, but now even if I boot up 2.4.26 I get the same problem.

* No console! - Works fine with 2.4.26 @ 1024x768, but 2.6.11.7 gives me a blank screen. Linux still boots, and I can log in and 'startx', at which point I get the X dispay. The settings are the same for each of the kernels .config files.

* My CDROMs (2 of) don't work - Apparantly gnome can't open /dev/hdb.

Can anyone please help? I've been up all night recompiling over and over! It's driving me mad.

Thanks,

norkers

1. did you install new alsa-drivers for kernel 2.6.11??? they are under /testing/packages/linux2.6.10
2. i don't know.
3. how your fstad looks like? if you were using hdx=ide-scsi you need to change some things in your /etc/fstab file...

gonna need a little more info on the cdrom part and the sound part (how did you configure your kernel)

for your framebuffer problem, you left out framebuffer support:
go to drivers->graphics support->console display driver support and pick the options you need ( at the very minimum you'll need video mode selection support and frame buffer console support enabled)

abisko00 · 04-25-2005, 04:29 AM

About the console: make sure that these parameters are set correctly:

Code:

CONFIG_INPUT=y
CONFIG_VT=y
CONFIG_VGA_CONSOLE=y
CONFIG_VT_CONSOLE=y

I read that it could happen that these settings are lost during kernel cloning.

norkers · 04-25-2005, 04:46 AM

thanks for the quick responses!

slackie1000, here's my fstab. no mention of anything scsi? also how do i go about upgrading ALSA?

Code:

/dev/hda6        swap             swap        defaults         0   0
/dev/hda5        /                ext2        defaults         1   1
/dev/hda7        /vfat            vfat        defaults,users,rw,umask=0 1 0
    1   0
/dev/hda1        /windows         vfat        defaults         1   0
/dev/cdrom       /mnt/cdrom       iso9660     noauto,owner,ro  0   0
/dev/fd0         /mnt/floppy      auto        noauto,owner     0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0
none            /sys            sysfs           defaults        0   0
/dev/hdb                /media/cdrom            auto    user,exec,noauto,comment 0 0

__J, framebuffer support is defo compiled (plus video mode handling, VGA 16 colour, VESA VGA and nVidia riva support) along with VGA test console and video mode selection support.

i configured sound in the kernel with sound card support (module), plus modules for ALSA & OSS.

abisko00, i checked out what you said and they are all present and correct.

any more ideas?

thanks,

norkers

hi there,

i don't know how is your previous installation from slack, but my suggestion is:

Code:

1. find a slack mirror 
2. go to /testing/packages/linux-2.6.10
3. download everything that starts with alsa
4. upgradepkg all of them

concerning your fstab file, looks a bit weird for me.
you have two cdrom drive. right?
afaik, /dev/cdrom is a link? can you check where is pointing?

Code:

ls -lrt /dev/cdrom

and keep posting...

regards

norkers · 04-25-2005, 05:26 AM

Hi,

I upgraded ALSA as instructed. No difference

I get the following when I run alsaconf...

Code:

modinfo: could not find module snd-opl3sa2
modinfo: could not find module snd-cs4236
modinfo: could not find module snd-cs4232
modinfo: could not find module snd-cs4231
modinfo: could not find module snd-es18xx
modinfo: could not find module snd-es1688
modinfo: could not find module snd-sb16
modinfo: could not find module snd-sb8

ls -lrt /dev/cdrom gives me.

Code:

lrwxrwxrwx  1 root root 3 2005-04-25 10:58 /dev/cdrom -> hdd

there's defo 2, a reader and a writer. if you look the second one is in /media. i've no idea how that's happened!

i have console now btw, i changed lilo.conf to vga=ask to do some testing and seem to be getting somewhere.

thanks,

matt

slackie1000 · 04-25-2005, 06:04 AM

hi there,

is it possible that alsa is compiled as built in your kernel?
do you have something special in your kernel?
alsa can not find your sound card module. i think it is not available in the kernel.
check your .config file. the slackware config for 2.6.10 kernel series has all the sound cards compiled as modules in the kernel.
this is a good idea if you don't know what is necessary for your card.
i didn't understand about the cds issue. is it solved?

regards

norkers · 04-25-2005, 02:34 PM

i'm working on the CDs now, i think it's a permissions thing...

my framebuffer device is all good. working fine now. it was the kernel!! you were right __J.

slackie1000, a question for you. it looks like i'm going to have to compile lots of the sound cards into my kernel and try and eliminate them one by one. should they be modules or actually compiled into it?

thanks,

norkers

norkers · 04-25-2005, 02:42 PM

still no luck

gnome is giving 'no volume control elements and/or devices' on startup.

alsa still finds no mods.

i have no /dev/dsp.

when i run alsamixer i get...

Code:

alsamixer: function snd_ctl_open failed for default: No such file or directory

hope someone can help.

slackie1000 · 04-25-2005, 02:53 PM

hi there,

let's concentrate in the sound card issue.
can you post the output of "lspci"???
also the ouput of

Code:

grep -i snd /usr/src/linux/.config

somehow you need to find your driver in the kernel and compile it as module. this is not required but highly recommeded....
do you have hotplug enabled? can you post the output of

Code:

lsmod

regards

lspci is in /sbin so either use su or just type

Code:

/sbin/lspci

Sound:

Quote:

plus modules for ALSA & OSS

When you say OSS, do you mean ALSA's OSS compatibility modules, or did you try and build both ALSA and OSS?

CD's:

Did you do anything like add SCSI emulation in /etc/lilo.conf for your CDs?

Something like "append=ide-scsi:hdc" (can't remember what it looks like)? If so, comment it out/remove it (it's no longer necessary in the 2.6 series), rerun /sbin/lilo and restart.

norkers · 04-25-2005, 06:29 PM

Hi,

okay, output from /sbin/lspci is...

I have compiled both ALSA and OSS as modules on my last kernel rebuild, is this wrong?

no mention of anything SCSI in lilo.conf

thanks,

Brian1 · 04-25-2005, 06:40 PM

Looks like you did not include the needed module for sound.
# CONFIG_SND_VIA82XX is not set

I not positive but recompile with this one as a module. If unsure make them all modules.
