This can happen when you have new kernel modules installed but are
running an older kernel image.  A new module may require a function
that is added in the new kernel image.  This particular function was
added in version 2.6.32-48squeeze2 as part of the fix for
CVE-2013-1773.

This can happen if you upgrade the kernel package but do not reboot
afterward, or if your boot loader is using an old kernel image for
some reason.
