No, the kernel is from a kernel.org, its not from another installation so it is 
fresh.


Where is the CentOS 5 kernel-xen ?

Here is the /etc/fstab

/dev/hda1        /             ext3     defaults,usrquota       1 0
none             /dev/pts      devpts   gid=5,mode=620 0 0
none             /dev/shm      tmpfs    defaults       0 0
none             /proc         proc     defaults       0 0
none             /sys          sysfs    defaults       0 0
/dev/sda2       swap           swap     defaults       0 0
/usr/tmpDSK             /tmp                    ext3    defaults,noauto        
0 0

Thanks!

Ian

Is your standard kernel config. modified from Debian?  If so, I will suggest 
that you use CentOS 5 kernel-xen config as base and modified from there to see 
whether are you able to reproduce the problem?

One important thing is due to udev version in CentOS 5, I think you will need 
to set/enable CONFIG_SYSFS_DEPRECATED and CONFIG_SYSFS_DEPRECATED_V2.

BTW, just curious what is your /etc/fstab looks like as the following make me 
curious... ...

Looking for driver for device hda1
Looking for driver for device hda2

Hope this helps!

Thanks.

Kindest regards,
