I am running 2.6.18-1.2798.fc6

Hi,

The best bet would be to actually submit this to the kernel.org mailing list.

Two reasons here, either kernel bug (post to kernel maintainer)
or Your memory is broken, test with http://www.memtest.org/

Tell us if it was broken memory or something else?

This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.
