Re: Kexec for ARM: Is it expected to load old kernels?

[Brian Smucker <bsmucker@anabaptists.org>]

Hi

So it appears I cannot load pre-2.6.24 kernels ARM kernels.  I have some 
further questions.

Is this an ARM-only thing?

If I want to load an arbitrary kernel, am I out of luck?

I thought theoretically kexec was able to execute arbitrary elf 
binaries, non-kernals, etc.  Is this true, or only my own misconception?

Or is it true in general, but not for ARM?

If it is not true for ARM, can I fix it?

I would like kexec to be able to boot old,old kernels, of the 2.4.16 
vintage.

Can you help answer these questions?

Thanks,

Brian
