kernel panic

kernel panic

[chiranjeevi vaka]

Hi all,

I am working on linux kernel tcp/ip optimization.
After doing some changes in my kernel, I am copiling
the kernel. While doing make xconfig, I have seleceted
some of known options and later as usual I have done
make dep;make bzdisk. 

The problem is while booting the kernel with my newly
developed floppy, I am getting the error message

kernel panic: VFS: Unable to mount root fs on 08:03

I donno what to do. Is it some thing related to "make
xconfig" options or some other thing. Please give me
suggestion.

Thanking you in advance
Murali.

I guess the obvious questions are:

What kind of filesystem are you trying to mount as root?  Have you
checked whether a root argument is being passed to the kernel by
whatever loader you're using?

Did you inadvertently disable support for that kind of filesystem?

If you're mounting root over NFS, did you disable support for 
any of the networking options you might need?  (like, say, kernel-level
IP autoconfiguration).

In short, what changed between the last configuration that worked,
and this one that doesn't?

Are you trying to mount a SCSI disk as root without having the correct SCSI
driver IN the kernel?

just a gues...
