Hello,
i am facing a problem here.
recently i installed RedHat Enterprise 4.6 64bit OS with kernel version 2.6.9-67. I wanted to upgrade the kernel to the latest version in order to install some qlogic drivers.

However i upgraded the kernel using the wrong procedure by doing "rpm -U". Now i am noticing some things that are not right such as only 1 processor showing in /proc/cpuinfo while there are supposed to be 2 x quadcore.

My question is what is the proper procedure to downgrade back to my old kernel 2.6.9-67? Thanks for the help.

You should be able to get the old kernel rpm and then install it using "rpm -ivh".

yup i downgraded using your method. But the processor information is still not showing correctly.

I followed the following link to properly upgrade the kernel back to .78 and all is fine now already.

Thats fine. Glad you managed to resolve the problem.

What's kernel version did you upgrade to?

Hi i upgraded from 2.6.9-67 to 2.6.9-78
