Yes, I looked at the buglist for the driver and didn't see anything
related. The NICs actually work just fine at moving data. And I have
the same NICs on several other Supermicros that do not have this problem.

Just for fun, I ran a backup on one of the machines, and not only did
the Ethernet work well, but the "phantom" load went away while a real
load was running. That's what leads me to suspect a kernel or timer
bug of some sort. There was a post on the Linode site about a year ago
about something that smells similar:
http://www.linode.com/forums/archive/o_t/t_2729/strange_load_average.html

But those guys are doing virtualization and using newer kernels that what
CentOS is distributing. 

I wonder if anyone else has seen this problem?

Thanks,
