[Mkdump-devel] mini kernel can't load?

[Hiromichi M. <hir...@so...>]

Hello, all.

I'm interested in mkdump, and now I'm testing it on my desktop PC.
But, it doesn't work fine...

Mini kernel looks booting correctly with stand-alone, but configure  
mkexec and
try"echo 2 > /proc/mkexec/stat", can't get dump. (Kernel panic  
messages and
"Starting mini kernel" were printed, but nothing like boot message  
was shown
thereafter, and there's no HDD access.)

My PC's environment is here.

OS: RHEL 4（kernel 2.6.9-34.EL） + mkexec kernel module
(use mkexec-module-3.0.tar)
MEMORY: 1024MB

Mini kernel is based on kernel.org's kernel 2.6.9  
(linux-2.6.9.tar.bz2), and compiled
it following the instruction of "README-v3". And, "minik_dump.o" is  
static linked.
(use minik-module-3.0.tar).

I have no idea which has problem mkexec kernel or mini kernel.
Will you give me some suggestions for it?

Thanks.
