Kernel Blocked

Kernel Blocked

[wei.li4]

Hi All,

First, if anyone wants to use linux 2.6.18-rc2-g73a589b5 with ppc, he 
should patch inflate.c from linux 2.6.18-rc7 to fix Uncompressing 
failure problem. But new problem is: when relocate and gunzip functions 
are finished, and 'Now booting the kernel' is shown, the system is 
halted. My bootloader is working fine with linux 2.6.13, could anyone 
tell me what the next function executes and how to check this kind of 
problem, thanks.

    I have a Xilinx ppc405 working out of the 2.6.18-rc7 linux-2.6 git 
tree - with patches for my board.
   
    I beleive you are either just at the end of the code in 
arch/ppc/boot/simple - which is mostly the initial load/decompress.
    Or just started the code in arch/ppc/kernel/head_4xx.S

    You ought to be able to grep "Now booting" to establish a last know 
good point.
    There is also a pretty good call tree in comments of 
arch/ppc/platforms/4xx/xilinx_ml403.c.
    While small parts are ml403 specific, much of it is generic.
    However, if you have not gotten into arch/ppc/kernel/head_4xx.S then 
you are not at the begining yet.
