Sorry for not providing details (was sure people will identify the 
problem in a glance).


Upgrade is from 2.6.17-r8

Attached the panic message:


VFS: cannot open root  device sda1 or unknown block (0,0)

please append a correct "root=" boot option.

Kernel panic - not syncing: VFS: unable to mount root fs on unknown - 
block (0,0)


Attached the .config file (after converted to 2.6.20-r8 - make oldconfig 
- just hit the enter key)

lilo is double checked. Below the relevant section.


boot=/dev/sda
root=/dev/sda1
read-only


image=/boot/vmlinuz-2.6.20-r8.v0

  label=SDA1-20-r8.v0
  append="root=/dev/sda1"
