Re: increasing memory alloted for 'init' during kernel boot.

[Prabhu Chawandi]

Hi ,

Thanks for the info...

Problem I am facing is, I have two bootloaders, when I boot from one
loader booting happens properly.

but when I try to load from other loader, kernel does not boot, it
crashes. When i saw the boot logs, I saw that I memory allocated to
'init' section in case of crash is short by almost 5MB to the normal
boot log.

I am using mips processor.

Any idea, why this might be happening ?

thanks,
Prabhu
