Howto install a debugging kernel in debian?

["Hans-J. Ullrich" <hans.ullrich@loop.de>]

Hello folks, 

I got the problem, that I need to install a kernel which creates debugger 
informations in dmesg.

I already built a kernel with activated debug, when I discovered, that debian 
already offers a package with built in debug: linux-image-2.6.39-2-amd64-dbg!

But when I installed this, there was only the no-debugging kernel below /boot.

Is there a non destructive and easy way to start the debugging kernel (which I 
found below /usr/lib/debug/ ), without to change my whole system? I just need 
to start this kernel only once, so I can send the kernel developer the needed 
dmesg file. After that I want to revert back to the running kernel.

You might understand, that I do not want to change (and possible kill) my 
system or working for hours and hours for only creating a simple dmesg 
message.

For those, who are interested in the kernel bug, take a look here:

Thanks for any help!

Best regards

Hans
