All,

I am running xen3.0.2  and xen unstable on RHEL 4, and get this error when trying to boot Xen kernel(domain0)
......
Creating root device
Mounting root filesystem
mount: error 6 mounting ext3
mount: error 2 mounting none
Switching to new root
switchroot: mount failed: 22
umount /initrd/dev failed: 2
Kernel panic - not syncing: Attempting to kill init!

Then system reboot.In grub.conf,I have change d the root=LABEL=/ to the actual device
(root=/dev/sda 3),and make the same change in /etc/fstab, but I got same error.

My system is Intel Xeon, Dual Core Machine, 2.8GHz. 32 bit Linux

my installation steps as below, 

# pwd
/home/vineet/xen-3.0.2
# make world
# make install
       
# cd /boot
# depmod 2.6.16-xen
# mkinitrd -f -v initrd-2.6.16-xen.img 2.6.16-xen

I have tried giving different options to creation of mkinitrd command but it doesnot work. I have tried "builtin" and "with" options and it doesnot worl. In addition, I have tried to make hyperthreading disabled,it doesnot work for me.

I have seen many such messages but no concrete solution to this problem. Please help.
