Ext3 users - Dec 2001 - kernel panic on ext3

Hello, Sir.

My name is Hiroyuki Kudo.
I have a problem using ext3 in my system DELL PowerEdge 1550.
I recently installed RedHat 7.2 (kernel-2.4.7-2) and found that it
used ext3. Later, since I needed to use nfsv4, I got 
kernel-2.4.4-nfsv4.  But it didn't start up and saying `kernel panic`
What is wrong with it?
If the problem can be cleared with ext3-patch, how can I do it?

You haven't told us when the panic occurred, or where, or what other
log messages were associated with it, so it is nearly impossible to
debug this: we need more information.

However, my guess is that your root filesystem is ext3, and you didn't
do a clean shutdown, so when you rebooted to the 2.4.4 nfsv4 kernel
(which does NOT have ext3), the kernel couldn't mount root.

Cheers,
