kernel panic (right forum?)

-0- · 12-07-2004, 01:06 PM

*i don't know if this is in the right forum, i wasn't sure, please move if wrong*

**warning, LONG post**

I'm attempting to compile a kernel to update to 2.6.9 from 2.4.26 (slack 10 default)

whenever i boot into this kernel i get the error:

"kernel panic - not syncing:VFS:unable to mount root fs on unknown-block(3,3)"

AFAIK all needed IDE and filesystem (i use ext2) drivers are installed properly in the kernel, it boots fine under 2.4.26 and windows.
i ran lilo to update the config, it's all compiled and copied to /boot as in :
digital hermit's kernel install guide (no link as i lack 5 posts)

I'm using a Compaq presario 2111ea laptop,

lspci gives:

my .config file for the kernel is (done with gconfig, builds perfectly) (i removed all the bits that are not set as otherwise the post is too long)

please, could someone help me here, at my wits end how to get this to boot. SOrry for the hassle, but i'm runnign out of ideas fast!

When I updated the kernel at home, make install copied vmlinuz (2.6.9) to /. Then I moved it to /boot and manually add to lilo.conf.

kevinalm · 12-07-2004, 01:24 PM

Don't know is this is your problem but there are a number of package dependancies going from 2.4.x to 2.6.x . Read the /Documentation/Changes file of the 2.6 kernel source. There are a number of tests to run. Looks like you've compiled in fs support, that's good.

-0- · 12-07-2004, 02:13 PM

Hmm , does it matter that i disabled the /dev filesystem

do i need to install somethign else to get that to work (i intended to use udev)?

otherwise i still can't think of any possibl solution, checking my config again now.

thanks

kevinalm · 12-07-2004, 03:19 PM

Ok, now the error message makes sense. There is no way to mount a filesystem if it's device file doesn't exist. So you either need to set up udev, devfs, or create real dev files. Afraid I can't help with udev/devfs. My personal opinion is that the genuis that dreamed those up ought to be flogged.

Seriously, I do understand the motivation (running short of distinct major/minor numbers) but I think that a three (or more) field solution of real dev files would have been better. Something like super/major/minor with the super number optional for backward compatability.

Anyway, that is what is causing the kernel panic. Without some sort of dev files for the partition, the partition isn't available to the kernel. Which then panics.

-0- · 12-07-2004, 03:37 PM

Right, i compiled a kernel with devfs, for now. i do have udev installed (slack 10 standard, i checked it was there,) but how do i set it up? as i want to get away from devfs if i can

can anyone help?

cheers,-0-

EDIT: the devfs kernel didnt work either....................running low on ideas now.........help!

kevinalm · 12-07-2004, 10:28 PM

I know there is one or more config files for devfs. The idea as I understand is to create needed dev files on demand. I think you may need an entry in fstab to mount the devfs. I can point you to a script that makes the most commonly used _real_ dev files if you like. But I imagine you want to try to get udev or devfs working, and like I said before I don't know those. (bump)
