this is my mkinitrd line.
 mk_initrd -k /boot/vmlinuz-2.6-xen -i /boot/initrd-2.6-xen

these are my grub lines

/dev/sda7?

 I am using SCSI.

>Most likely the problem is that you did not include the drivers for 
your disks in the kernel or initrd.  mkinitrd --with=modulename  where 
modulename is the module for your disk, I believe, is one way to solve
the problem.  Another is to re-compile your kernel with CONFIG_MODULE=Y (*
in menuconfig)

 This CONFIG_MODULE is already set to Y.

>(oftentimes I find it is easier to troubleshoot these sorts of errors 
w/
a 
serial console... if you could paste the boot messages, finding your 
problem would be trivial-  with the information you are giving me, I'm 
largely guessing.)


>also, you should mention what distro/version you are using.  
RHEL/CentOS

I am using SLES10 GMC.

>doesn't like to boot at all without an initrd, whereas on debian or 
slackware, I usually just compile everything I need to boot into the 
kernel and run without initrd.
