Unhappy how to revert back to the previous kernel version?


I am havin an IBM eserver x255 which has been installed with red hat advanced server 2.1. By default the kernel version was e3 n later i upgraded it to e27. I have 2 broadcom gigabit cards. Previously they were working fine (when the kernel ver was e3). but later when i upgraded it to e27 they fail to work.
wat must b the reason behind this?
now i want to revert back to the previous kernel. how do i do that?
or can anybody pls guide me to the latest broadcom drivers which support e27 kernel.
thanks in advance...

How did u upgrade your kernel via rpm or did u compile the kernel from source. If u upgraded through rpm there should a extra entry on your grub menu so th at u may select the older kernel. Now if this does not appear that u did it via rpm therefor Im guessing u compiled it from src. if that is the case and u have not deleted the old initrd-<kernel version>.img and the vmlinux-<kernel version> which will be found in the /boot dir then all u have to do is edit the /etc/grub.conf file and make it piont to those two files, this should resolve the issue in booting the older kernel version. If u have compiled from src I suggest that u recompile kernel and select the NIC drivers u need for it to work with the new Kernel.

Try these things first

then the only way to use the new kernel with those NIC Drivers u have to download the kernel src code and comp+ile those drivers into the new kernel.

Try these cmds first thow to check if maybe the modules r not running already. lsmod and lspci see if u see any refreance to the NIC u have. Also cherk in the /etc/modules file for any referance.
