VFS-boot-issue
 
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

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 don't use gentoo but I think the new kernel does not need emulation for cdwriters anymore.

cull the "ide-cd dev=/dev/hdc " kernel append and see if that makes a difference.....you may boot but then find your burner works or you cuss me

Hello aus9,

thanks for your hint - I can boot now without any problem.

But I have to admit I don't know if it was the upgrade to the Gentoo-Kernel 2.6.10-r5 or the editing of the grub.conf which made me happy :-).

Thanks
dranath
