another kernel panick: mount root fs

xushi · 09-22-2004, 12:21 PM

Help =/

I just recompiled my kernel, with the settings i have (btw i recompiled from /usr/src/linux, not /usr/src/linux-2.4.26, if that makes any difference)

Now, i keep getting

kmod: failed to exec /sbin/modprobe -s -k block-major-8, errno=2
VFS: Cannot open root device "801" or 08:01
Please append a correct "root=" boot option
kernel panic: VFS: unable to mount root fs on 08:01

The root boot option should be correct, here's my lilo conf:

Code:

# LILO configuration file
# generated by 'liloconfig'
#
# Start LILO global section
append="hdc=ide-scsi hdd=ide-scsi"
boot = /dev/sda
#compact        # faster, but won't work on all systems.
#prompt
timeout = 5
# VESA framebuffer console @ 1024x768x32k
vga = 790
# Normal VGA console
# vga = normal
# VESA framebuffer console @ 1024x768x64k
# vga=791
# VESA framebuffer console @ 1024x768x32k
# vga=790
# VESA framebuffer console @ 1024x768x256
# vga=773

# VESA framebuffer console @ 640x480x256
# vga=769
# ramdisk = 0     # paranoia setting
# End LILO global section
# Linux bootable partition config begins
image = /boot/vmlinuz
  root = /dev/sda1
  label = Slack10
  read-only

image = /boot/vmlinuz.old
  root = /dev/sda1
  label = slack.old
  read-only
# Linux bootable partition config ends

Booting from Slack10, slack.old should still have my old boot, And btw im booting from SCSI (sda1). I followed the kernel compile for newbies on top of the forum.

Any suggestions?

Double-check that you compiled support for SATA and your filesystem built-in in the kernel NOT as module.

SCSI disk supprt (y)
SCSI low-level drivers -> Adaptec AIC7xxx supprt (m)

EDIT: File Systems -> Ext3 Journaling file system support (y)

EDIT2: Sillicon Image chipset support (y)
SiS5513 chipset support (y)

But i didn't modify the kernel before this, so shouldnt it work with the settings it currently has if i recompiled it, like what i did now?

Bah... why do i have
vmlinuz
vmlinuz-ide-2.4.26
vmlinuz.old

in /boot .........?! I assume the kernel would know im booting from SCSI in its configuration when recompiling.

gbonvehi · 09-22-2004, 12:49 PM

Sorry i thought "the settings i have" were your machine settings, not the current kernel ones, anyway, try changing SCSI low-level drivers -> Adaptec AIC7xxx support (m) to built-in (the (m) indicates a module while a (*) indicates built-in).

gbonvehi · 09-22-2004, 12:50 PM

vmlinuz-ide-2.4.26 is the default slackware kernel while vmlinuz is a link to it in the installation, i'm sure you overwrited the link with your recently compiled kernel so don't worry about it as long as you've also copied System.map-ide-2.4.26 to System.map.old

Thanks, ill do so and recompile. Ill be back =)

Question though... i cant get lilo to display a selection of which kernel to use in bootup.. how can i fix that? it would make life easier to finish my work through the old boot.

gbonvehi · 09-22-2004, 01:23 PM

Change timeout = 5 to timeout = 150

xushi · 09-22-2004, 05:51 PM

Thanks, i got the kernel back up and memory is now 1G

However, as usual i lost my damn sound =/
The mobo is an Asus A7N8X Delux with onboard Nforce 2, but i prefer using the intel i80 sound module...

its compiled in the kernel, and found in /lib/modules/2.4.26/kernel/drivers/sound
however i fi
modprobe i810_audio
modprobe: Can't locate module i810_audio.o

insmod i810_audio
i810_audio.o: unresolved symbol ac97_probe_codec
i810_audio.o: unresolved symbol unregister_sound_dsp
i810_audio.o: unresolved symbol ac97_alloc_codec
i810_audio.o: unresolved symbol register_sound_dsp
i810_audio.o: unresolved symbol register_sound_mixer
i810_audio.o: unresolved symbol unregister_sound_mixer
i810_audio.o: unresolved symbol ac97_set_dac_rate
i810_audio.o: unresolved symbol ac97_set_adc_rate
i810_audio.o: unresolved symbol ac97_release_codec

Any suggestions? =/

Edit: lsmod | grep soundcore outputs
soundcore 3396 0 (autoclean)

My apologies, I read around and the sound i want to work is Alsa's intel8x0, and not OSS i810_audio.

Hmm, im not sure if i should start a new thread for this or not.
