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

[Aleksander Adamowski]

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

Feb 17 14:05:12 domzero2 kernel: Bridge firewalling registered
Feb 17 14:11:54 domzero2 kernel: Could not allocate 8 bytes percpu data


Are those messages dangerous?
