Here's something jbernardo wrote in topic for Jaunty: I just want to add that for those having problems with makedumpfile like the “get_debug_info: Can’t create a handle for a new debug session” because you removed kernel debug info while configuring it, you can pass “no_dumpfile=true” the same way you pass “skipabi=true” in the build line.

I want to use the same kernel-source i used for the previous kernel i made, but i want to use the original config file i had in the 1st place. So basically im asking you to tell me what i need to do before repeating the same process again on the same system just so that i don't face any hiccups while i'm at it. :) Hey nice tutorial, i followed some of your explanations and got a succesfully working kernel, i just wanna ask that now i want to create another kernel, do i have to remove the 2nd kernel and if not, is there anything i need to do like cleaning up for instance before restarting the process or can i go ahead and begin customising and compiling my 3rd kernel.

This test system is recent, from last 3-4 months. I have done a few updates and stock kernel updates. Other than that, this is basic system. I only started doing the kernel compile on it. And did it by using these kinds of instructions to keep my custom kernel separate from current and future stock kernel updates. ken@ken-ubuntu:~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 9.04 Release: 9.04 Codename: jaunty ken@ken-ubuntu:~$ That worked!

The reboot problem occurred with the default kernel as well. Not sure what changed to make it work normally again. I just rebooted and everything is normal, I see my BIOS startup.
