SubjectBooting Linux using initrd
Hi Folks,

I am trying to boot a Real Time Linux on a MIPS RC32334 based
board using initrd feature and i am trying to mount the RAMDISK as
my root file system. The boot sequence is not successful. I
get some errors. Please find in this mail the log of the Kernel.
Also find the information of the ramdisk.o that I have
integrated
with the kernel. I will be grateful if you can spend a little of
your precious time in helping me fix the problem.

Kernel version that i am using is 2.4.5-pre1.

Sorry for troubling you.

Thanks in advance,
Nanda
