hi all,
After installing linux kernel 2.4.19, the following boot error occurred:


kmod: failed to exec /sbin/modprobe -s -k block-major-22, errno = 2
VFS: Cannot open root device "hdc2" or 16:02
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 16:02

The GRUB conf file has:

kernel=(hd0,0)/vmlinuz root=/dev/hdc2
initrd=(hd0,0)/initrd-2.4.19.img

can u give me a solution.

thanx,
bye,

Hi.
Is it possible that support for the specific filesystem of your /dev/hdc2 (ext2 ? ext3 ? reiser ? xfs ?) has not been included with your kernel ?
The support for the root-filesystem should NOT be compiled as module, but should be fixed into the kernel, since without the root-filesystem (hosting /lib/modules), no modules to (evt. auto-)load when accessing a specific filesystem, can be found (sth. like a chicken-egg problem).

hi there

are u not able to boot any of ur OS
and have u changed ur grub.conf manually???

because i find reference to

hda--primary master

and

hdc--secondary master in ur grub

regards

I am receiving the same error:

VFS: Cannot open root device “hdc2” or 16:02
Please append a correct “root=” boot option
Kernel panic: VFS: Unable to mount root fs on 16:02

I am a newbie and am tried to build my own kernel on my debian machine. My goal is to get WiFi on my Dell Inspiron 5150 laptop. I did a base install of debian using the netinstaller, and have added only the packages outlined for making my own kernel. I used the 2.4.27 kernel. I have followed the instructions for rebuilding my kernel, and for setting up WiFi. When I was choosing options after "make menuconfig" I selected Reiser filesystem support to be built into the kernel.

Please help. I am sure that I am doing something incorrectly, but I am not sure what or how to fix it.
By the way the old image "2.4.27-2-386" still works.
