RE: compiled new kernel to see if machine won't freeze



I saw a link in one of the emails here in the list, and I went to it:

http://fedoraproject.org/wiki/Common_kernel_problems

There I saw how to take an initrd apart: and I did that comparing the one from the compiled kernel and the one from fedora, this is what I encountered.

As I was going to click send on this message, machine froze again :(
Good thing yahoo saved it as a draft and now I can send.

Question now becomes how can I fix the initrd so that the new kernel can at least boot, and then determine if it or if it will not freeze the machine.  I appreciate your input.  

Regards,

Antonio
