If inside a xen machine you try to do a chroot into a directory and get this error:

Inconsistency detected by ld.so: rtld.c: 1192: dl_main: Assertion `(void *) ph->p_vaddr == _rtld_local._dl_sysinfo_dso’ failed!

One of the possible solutions is to use the following command before issuing the chroot.

echo 0 >/proc/sys/vm/vdso_enabled

It is supposed to have some (unknown to me) security issues though.
