Fedora xen - Feb 2006 - Xen on x86_64 and "Could not allocate 8 bytes percpu data" kernel messages

I''ve just booted an Opteron HP Proliant server into 
2.6.15-1.1955_FC5hypervisor fo x86_64.

The machine has booted and network communications are working, but there 
were a couple of suspicious messages on the console during bootup:

"Could not allocate 8 bytes percpu data"

Here''s a longer excerpt from the logs:

Feb 17 14:04:46 domzero2 kernel: EXT3 FS on cciss/c0d0p3, internal journal

Are those messages dangerous?

Depends on where they are coming from.  I''ve seen one instance myself
(also on the 1.1955 x86_64 dom0), so I''ll have a look into this.

If you want to open a bugzilla against kernel-xen, getwill help us to
make sure this doesn''t get missed!

Thanks,
