I have a RedHat EL4 desktop. I try recompiling new kernel 2.6.25 myself and able to follow steps from http://www.cyberciti.biz/tips/compil...kernel-26.html
When I boot with the new kernel, I get an error
Booting the kernel,
Red Hat nash version 126.96.36.199 startin
Reading all physical volumes. THis may take a while...
No volume groups found
Unable to find volume group "VolGroup00"

Kernel panic -- not shyncing: Attempted to kill init!
I am not sure what all this mean... it worked with the old kernel if I switch back.
