kernel panic

[venkatkk]

i just compiled the latest 2.6.20 kernel on my FC5 box ...but am getting kernel panic on rebooting with the new kernel...i get the following error messages

Unable to access resume device(LABEL=SWAP-sda10)
mount : could not find filesystem '/dev/root'
setuproot : mounting /dev failed:no such file or directory
setuproot : error mounting /proc:no such file or directory
setuproot : error mounting /sys failed:no such file or directory
switchroot: mount failed
kernel panic - not syncing: attempted to kill init

moreover when i select my old kernel at the grub prompt it boots fine..its just the new kernel...any help would be greatly appreciated ..thanks....

i am not sure if i did the mkinitrd right...this is what i did...

mkinitrd /boot/initrd-2.6.20.img 2.6.20

fdisk -l shows this...

post the contents of grub.conf file.

..heres my grub.conf...


[root@localhost ~]# cat /boot/grub/grub.conf
# grub.conf generated by anaconda

# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that

its the first one 2.6.20.1 thats giving the problem...

[devils casper]

grub.conf

kernel /vmlinuz-2.6.20.1 ro root=LABEL=/ rhgb quiet
initrd /initrd-2.6.20.1.img

fdisk -l
/dev/sda9 17849 17861 104391 83 Linux
/dev/sda10 17862 17990 1036161 82 Linux swap / Solaris
/dev/sda11 17991 19456 11775613+ 83 Linux

there is any LVM ( Linux extended partition ) listed in output of fdisk -l command but grub.conf is refering to LVM only. change value of root in kernel line.

kernel /vmlinuz-2.6.20.1 ro root=/dev/sda11 rhgb quiet

edit /etc/fstab file too.

sorry i am a bit of a newbie what exactly do you want me to edit in /etc/fstab......

[venkatkk]

here are the new contents of my grub.conf and fstab...

i still get the same annoying messages...ive actually compiled a newer version of the kernel 2.6.20.1...no luck....

[devils casper]

if earlier version is booting up correctly then no need to mess with grub.conf or /etc/fstab file. problem is in Kernel Compliation only. did you change anything in default config?

[venkatkk]

...um yes i included support for ntfs as a module....i read on the net somewhere that make install usually comes thru without problems..i am doing it manually currently...

$ cp arch/i386/boot/bzImage /boot/bzImage-KERNEL_VERSION
$ cp System.map /boot/System.map-KERNEL_VERSION
$ ln -s /boot/System.map-KERNEL_VERSION /boot/System.map

should i go ahead and do a make install ..i mean what will happen to my old vmlinuz and initrd files and the corresponding entry in grub if i do go ahead and do make install...
