 |
|
Hello Forum!
I just tried to upgrade my Kernel from 2.6.9-r3 to 2.6.9-r9 but after the whole process (make clean; make menuconfig; make; make modules; make modules_install; modules-update; cp arch/i386/boot/bzImage /boot/[Kernelname]) I recieve following error-message:
| Code: |
VFS: Cannot open root device "hda3" or unknow-block(3,3)
Please append a correct "root" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3,3)
|
But one very odd thing strikes me: When I compare the Kernel-configuration-files of my newly compiled 2.6.9-r9-Kernel with the one which I had running (2.6.9-r3 which is still running without any problems), the only difference is the USB-Network which I compiled as a Module to connect my Sharp Zaurus SL-6000L to my Gentoo-Box.
Here's the diff-output:
| Code: |
diff .config-2.6.9-r3 .config-2.6.9-r9-zaurus
3,4c3,4

As you can see, I only activated USBNET to be compiled as a Module.
Don't know if it helps, but here's my grub.conf:
| Code: |
# Boot automatically after 10 secs.
timeout 10
# By default, boot the first entry.
default 0
title Gentoo 2.6.9
root (hd0,0)
kernel /boot/kernel-2.6.9 root=/dev/hda3 ide-cd dev=/dev/hdc vga=6
title Gentoo 2.6.9-r9 ipod zaurus
root (hd0,0)
kernel /boot/kernel-2.6.9-r9-zaurus root=/dev/hda3 ide-cd dev=/dev/hdc vga=6
#title Failsafe
#root (hd0,0)
#kernel /boot/kernel-2.6.9 root=/dev/hda3 ide-cd dev=/dev/hdc vga=6
#initrd /initrd.img

Can anybody help me out? I'm quite flabbergasted...
Thanks in advance

I'm having a similar problem...going to look into this later today when I have time. Hopefully somebody replies to this thread before I find a solution on my own 
I get the same exact error message except my root partition is on /dev/hda2. Could it be a problem with a module in the kernel?

the redundant but good suggestions:
make sure your ide/sata/etc drivers are compiled in
make sure your fs is compiled in
verify your grub config with your partitions etc

I have been trying to get a 2.6.9 or 2.6.10 to boot for about two months and only got one, 2.6.9-rc4-mm1. And I only got it to boot with one version of the kernel and have not been able to reproduce that behavior at all.
None, repeat, none of the kernels I have tried since 2.6.9-rc4-mm1 will boot successfully. It has something to do with udev but on my machine it happens too fast for me to figure it out. (Dual Athlon, 1GB RAM, 3ware-7xxx SATA with WD disks) My working kernel, 2.6.9-rc4-mm1 uses devfs which is now depreciated and not even in 2.6.10, so it kind of appears that we are in a pinch. I guess none of the developers have SATA disk since it works fine on my laptop with IDE disk.

I got the kernel to boot up for me. It must be a bug with one of the modules for some form of usb support. I was using an old config from one of my debian machines (had alot of modules in it that I really don't need). I just disabled all of the modules for this USB support for miscellaneous devices that I don't use. And now it boots.
please note:
 my grub.conf was correct
all filesystems *were* compiled in to begin with
ide,sata,chipset support and all that good stuff were enabled
But yes, redundancy is definetly good for a situation like this.
