11 PaX only logs bad behaviour when it's about unintended code execution,
12 this bug here is a kernel-internal consistency check, it doesn't mean
13 that the triggering userland app has a bug, it may very well just manage
14 to trigger a kernel bug (which in turn could be in PaX for all i know).
15 it'd be nice if you could find a way to reproduce it, also if you could
16 test with 2.6.23-pax.
