Also reported here: http://linux.derkeiler.com/Mailing-Lists/Kernel/2007-11/msg08255.html, which alludes to a possible issue with PaX. However, the version of the kernel under due consideration is now obsolete. Jason, please confirm as to whether the bug is still in effect as of the latest stable version of hardened-sources (2.6.25-r8 at the time of writing).
