Question
Upgrading Linux Kernel
Hi all,
I want to upgrade Linux Kernel. I currently have Kernel version 2.4.21-4 and i want to upgrade to 2.4.21-20. I downloaded the rpm and installed it by the following command:
$ rpm -ivh kernel-2.4.21-20.EL.i686.r
Now when i restart system and select kernel ver kernel-2.4.21-20 i got the following error on startup.
Creating block devices
VFS: Cannot open root device "LABEL=/" or 00:00
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 00:00
Am i missing some steps regarding upgrade.
