I am running RHEL 3 with kernel linux-2.6.14.6-grsec. I have been trying to upgrade (or go to the 2.4 branch) with no luck.
I tried the latest 2.4 RPM from RH, 2.4.21-47. I used the lilo -R switch so it could be restarted if the kernel failed. The server never came back and had to be rebooted into the previous kernel.
I tried compiling a generic 2.6 kernel following the guide at eth0.us - http://www.eth0.us/generic-2.6.10 - of course using the latest stable version (2.6.17.7), not 2.6.10. It compiled fine, installed fine, lilo accepted it. Again used lilo -R to set the bootup image. But it didn't come back up on a reboot, same as the 2.4 I tried.
There's nothing but a big time gap in /var/log/messages, and I can't find any logs that report anything.
Am I missing something here? Any ideas?
How would I go about troubleshooting this?
