# Error facing :------
kernel panic - : not syncying , VFS : Unable to mount root fs on 
un-known block (3,5)
------------------------------------------------------------------------------------------------------
# Machine and kernel architecture:-----------

Default Working installed kernel - vmlinux-2.6.5-7.97
Xen dom0 kernel - vmlinuz-2.6.12.6-xen0
------------------------------------------------------------------------------------------------------
# Steps followed..to run the kernel.
I have builded Xen 3 kernel (2.6.12.6) on x86 architechture with IDE 
support and kernel vmlinuz-2.6.12.6-xen0 is working fine in the builded 
x86 architecture machine.
My requirement is to run the above kernel in AMD architecture by copying 
the same from x86 to AMD.
I copied below files and creared initrd image.
------------------------------------------------------------------------------------------------------
Files are :
System.map-2.6.12.6-xen0
vmlinuz-2.6.12.6-xen0
xen-3.0.0.gz
------------------------------------------------------------------------------------------------------
Created initrd by command (Successfully):

# mkinitrd -k vmlinuz-2.6.12.6-xen0 -i initrd-2.6.12.6-xen0
Root device:    /dev/hda5 (mounted on / as reiserfs)
Module list:    reiserfs

Kernel image:   /boot/vmlinuz-2.6.12.6-xen0
Initrd image:   /boot/initrd-2.6.12.6-xen0
Shared libs:    lib/ld-2.3.3.so lib/libc.so.6 lib/libselinux.so.1
Modules:        kernel/fs/reiserfs/reiserfs.ko
Bootsplash:     SuSE-SLES (1024x768)
------------------------------------------------------------------------------------------------------
my grub file entry is (Using suse - /boot/grub/menu/lst):

title Linux XEN 3.0
   kernel (hd0,0)/xen-3.0.0.gz dom0_mem=256024 ramdisk_size=16384 noreboot
   module (hd0,0)/vmlinuz-2.6.12.6-xen0 root=/dev/hda5 selinux=0 
splash=silent resume=/dev/hda2 elevator=cfq showopts
   module (hd0,0)/initrd-2.6.12.6-xen0

------------------------------------------------------------------------------------------------------
Still facing the Error :kernel panic - : not syncying , VFS : Unable to 
mount root fs on un-known block (3,5)
Any help...
Thanks

Arun
