RHEL 4.6 kernel downgrade
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.
