I have a machine with a recent install of centos (2.6.32-220.2.1.el6.x86_64 kernel). It crashed 3 times this week, and sent emails like the one below complaining about kernel taint. I've gone back to a previous kernel to see if that helps, but otherwise I don't know how to investigate this. What should I do?

Ignore it.
Here's stuff from the log and one of the emails:
