Details:

When attempting to boot a Xen guest using legacy_configfile
/boot/grub/menu.lst the following config is generated:


set root='(hd0,1)'; set legacy_hdbias='0'                                     
                                         
legacy_kernel   '/boot/vmlinuz-3.16.0-4-amd64' '/boot/vmlinuz-3.16.0-4-amd64' 
                                         
'root=UUID=38420e46-6123-477d-ba23-baeba8ac0d59' 'ro'                         
                                         
legacy_initrd '/boot/initrd.img-3.16.0-4-amd64'
'/boot/initrd.img-3.16.0-4-amd64'


That comes from the following menu.lst:


default         0                                                             
                                         
timeout         5                                                             
                                         
color cyan/blue white/blue

root            (hd0,0)

root=UUID=38420e46-6123-477d-ba23-baeba8ac0d59 ro                          
initrd          /boot/initrd.img-3.16.0-4-amd64


The guest fails to boot with the following output:


[    1.470403] Freeing unused kernel memory: 216K (ffff8800017ca000 -

[    1.473384] Call Trace:


The problem seems to be the repeated file name on the "legacy_initrd" line.
Editing the generated config and removing that second file name allows for a
normal boot.

This has been discussed on grub-devel in this thread
