kernel panic on booting

charlie_lab · 03-29-2010, 11:03 AM

hello,

I have done everything on the book 1.1.0 Pure64.
But when I boot my new system I get this message :

Cannot open root device "1602"or unknown block (22,2)

Fdisk shows this

/dev/hdc1 swap
/dev/hdc2 / reiserfs.

Lilo.conf looks like this :

boot = /dev/hdc2
lba32
prompt

image /boot/lfskernel-2.6.33.1
label lfs
read-only
root /dev/hdc2

Reisferfs is enabled in the kernel.

What went wrong here ?

Hello,

I use sata_sil for the hard disk.

what kind of filesystem are you trying to boot from?

this might solve your error.
"linuxfromscratch.org/lfs/faq.html#unable-to-mount-root"

at the moment i am getting the same problem but i have my root partition on a ext3 filesystem. The kernel can not seem to boot it. I am recompiling the kernel with ext3 support so hopefully when i reboot it will work

the error i get is "vfs cannot open root device sda3 or unknown-block 2 0"

Hello,

I try to boot from reiserfs.

And the faq didn't help. I checked all the things already several times.

i fixed my problem today. I only had the general scsi support enabled. i had to enable the controller i had on my machine in the kernel.

cool.
