Slackware 10.2 recompile error


I am new to linux and in need of some assistance. I am using Slackware 10.2 on a DELL XPS M140 (1.86 processor, 2g ram).

I have looked through several guides on this site (they are all great) and keep encountering errors upon boot. here it is -


VFS: Cannot open root device "308" or unknown-block(3,8)
Please append a correct "root=" boot option.
Kernel panic - not syncing: VFS: unable to mount root fs on unknown block(3,8)


i have tried using make oldconfig, i tried using make xconfig and loading the 2.4.31 kernel, tried the default setup from 2.6.17 and also tried to modify it somewhat, but still to no avail.

can anyone please help? do i need to post more info?

Hi, and welcome to LQ!

That info is indeed a bit insufficient. It would be good to hear
what kind of HDD controller that thing uses (PATA, SATA), ideally
with the chipset ...

Also it's not quite clear whether that problem only occurs with one
kernel, and how you managed to "tried the default setup from 2.6.17"
... can you actually boot the machine by some means, and are able to
recompile your kernels?


Cheers,
Tink

P.S.: I'll shuffle this thread to the Slackware forum where it's going
to have better exposure to the right people :}

Taking a shot in the dark here ....

When I have seen that error in the past it is usually because a filesystem driver that is needed for booting the system is either not compiled at all or compiled as a module. If you know what type of filesystem you are trying to boot into (ext2 or rieser, etc.), try building it into the kernel itself and not as a module.

thank you for helping me out.

when i opened 'make xconfig' there were alot of different options preselected to be compiled or installed as modules, i had assumed it was a default 2.6.17 config. i had also tried copying my 2.4.31 config to the /usr/src/2.6.17 directory and loading that with xconfig and that did not work either.

sorry about the lack of info about my system, i am not entirely sure what i need to post, hopefully the following will be sufficient.

i am using ext3 fs. (i compiled ext2 and ext3 into the kernel on each attempt)

Hi,
This sounds like what I was getting when I went from 2.4.31 to 2.6.16.22.
There is someting in the README.initrd file in the kernel packages directory
that helped me. My root partition is reiserfs, and needed a ramdisk loaded
prior to accessing it.

The file is located at /slackware-current/testing/packages/linux-2.6.17.4/

This is the excerpt that I used, but you will want to read the whole file:

Quote:
Change into the /boot directory:

cd /boot

Now you'll want to run "mkinitrd". I'm using reiserfs for my root
filesystem, and since it's an IDE system the reiserfs module will be
the only one I need to load:

mkinitrd -c -k 2.6.17.4 -m reiserfs
I hope this helps.
-CD-

When I first installed Slackware onto my laptop, it was the 2.4 kernel. When I then tried compiling the 2.6 kernel, I did what you did and used the 2.4 config file as a basis. I'm not sure if that was a good idea or not since I then ended up spending about two days recompiling my kernel to get everything I needed correctly compiled into my kernel.

The advice that CoolDave is correct only if you've compiled your filesystem drivers as a module and need to load it on boot-up before you've fully mounted your filesystems. By default, Slackware's config only supports ext2 with no initrd. However, if you've compiled ext3 support into your kernel, then theoretically, you shouldn't need an initrd.
