I'd suspect it's possibly hardware related:

http://www.kerneloops.org/search.php?search=free_block&btnG=Function+Search

Look at the very similar call signatures - spanning almost all
kernels back to v2.6.16. There's one spike at .27 - perhaps the same
box trying up hard and crashing several times - or a popular distro
kernel?

Or it's a really ancient bug going back to v2.6.16.
