Installing 2.6.3 on RH9

[Douglas Phillipson]

I recently tried 2.6.3 and it appeared to work fine but 2.6.4 won't 
boot. When booting it says it can't mount root as ext3.

I have ext2/ext3 compiled in the kernel, it's not a module.  The exact 
error is:

Creating root device
Mounting root filesystem
Mount:  error 6 mounting ext3
pivotroot: pivotroot(/sysroot,/sysroot/initrd) failed: 2
umount /initrd/proc failed: 2
Kernel panic: no init found.  Try passing init= option to kernel


What is so different between 2.6.3 and 2.6.4 that would cause this?


Here is GRUB entry:

title Red Hat Linux (2.6.4)
         root (hd0,1)
         kernel /boot/vmlinuz-2.6.4 ro root=/dev/hda2
         initrd /boot/initrd-2.6.4.img


Many Thanks
