[uml-user] UML Fedora Core3 Boot Failed

[Louai Al-A. <lo...@cc...>]

Hi all,

I ran my UML with Kernel 2.6.8 on RH8 and root_fs for FC2 and it worked all
fine.

 

I used the same linux binary and root_fs on FC3 , bit it did not boot.

I recompiled the linux binary again on FC3, but the problem was not solved.

Below is the output I got.

 

Thanks in Advance
