Comment 2 for bug 132425

It turns out that the bug is due to the Xen kernel.

Basically you need to set "hwcap 1 nosegneg" in /etc/ld.so.conf.d/xen.conf

As per https://kerneltrap.org/mailarchive/linux-kernel/2007/11/28/455534/thread

I am only recording this here because I just spent a frustrating number of hours when hitting the same bug -- and perhaps this can help someone else out in the same situation.

Additionally you probably want to also upgrade the kernel as well.
