Dear All,

I have a Centos 5.2 server used as a squid proxy server for quite sometime and was workin fine

after a power failure the system refused to boot

i jus see the grub boot load screen n then hangs

so using the space bar n with the arrow keys i selected my earlier kernel and it booted fine

i think that the latest kernel file i have that isvmlinuz-2.6.18-92.1.17.el5xen is corrupted.

how could i restore it back

will yum upgrade solve the problem

appreciate ur help

Since the system boots with the older kernel, you could try removing and re-installing the non-functioning kernel. This is the easiest way to get the kernel and the initrd replaced. Make note of any custom settings you might have for that kernel in the grub.conf file.
