linux 2.6.16.1 and kdb "error 6 mounting ext3"

[Rohan Mutagi]

Hey Guys,
 I am getting a -

"Kernel panic - not syncing: attempted to kill init!"

error when I try to run 2.6.16 kernel compiled with kdb support. Any
ideas how to proceded further into this problem?

Steps I took were:
1. Got a fresh 2.6.16.1 kernel
2. Applied the kdb patch from ftp://oss.sgi.com/www/projects/kdb/download/v4.4/
3. make clean; make; make modules_install install; reboot;

I am running this Linux RHEL inside VMWare. Now when I reboot to the
2.6.16-kgb kernel..
I get the following error after I choose the 2.6.16 kernel from grub!

I an provide the screen shot(60k), but not sure if posting screen

However, when I boot up with the older kernel. everything works fine.
Any ideas whats the problem or how to proceed further?

Thanks a lot for your time,
Rohan Mutagi

This is appear to be a kdb problem.  The problem is that lvm could not
find the volume groups, the kdb patch does not touch lvm.  Just to be
sure, backout the kdb patch and rebuild, but I doubt it will make a
difference.

Typo, should be 'This does not appear to be a kdb problem'.
