.config KVM+rsbac+PaX

Hi folks, the bug I sent to gentoo hardened mailing list, this one (
http://www.gossamer-threads.com/lists/gentoo/hardened/274662)

has reproduced from ebuild from Anthony Basile (3.4), with the latest
kernel 3.10 with PaX. I think it's unusual that the same bug hits twice in
two so distance in time kernels and so different from their other.

It's not related with PaX neither ACPI since I disabled both and bug
reappeared. Have anyone a .config that belongs to a guest linux 32bit KVM
virtual machine without this trouble?

Since I think it's a kernel bug (since when bug hits system gets unusable
and any execve syscall from there get segfaulted, forcing to do a hard
reset, I would like to test one "working" .config to try to isolate which
CONFIG_* has been playing with my mind health.

Thanks for your attention.
