Pointers on debugging my machine not booting

[Gideon D'souza]

Hey guys,

So I usually have the latest mainline kernel (on my fedora box) I've
recently sent it tiny refactoring patches.

Today, I start my machine and it just doesn't start. I had 3.11, 3.12,
and a few 3.14 rcs.

All show up booting, a few lines print on the screen about various
things it does. At some random point the screen is just black and
backlit and nothing happens. I tried all kernels, 3.11 and 3.12 and
official fedora supported kernels. The rest I installed. Even the
fedora rescue system doesn't work.

I tried looking into remote debugging linux and keep just getting hits
on virtual machine options. It's time I left my training wheels and I
want to debug my actual machine and see what's going on.

Several of those kernels have debugging support on. I just don't get
what wire I need to buy, what really is a JTAG and I just need a
pointer on how to set it up. I have another windows machine and an OSX
machine around.

Any pointers (pun intended) will be greatly appreciated.

Regards,
Gideon
