build2.osmocom.org hardware replacement

Hi all,

during the past couple of days, there have been a high number of build failures due to 'illegal instruction'. I checked about a handful of them, and they all happened on build2.osmocom.org.

On the machine nothing strange could be observed, i.e. no oopses or the like. Also, debsums didn't report any broken compiler binaries.

I've taken the builds slaves offline and asked for the machine to be replaced (disks will be moved so no data loss expected).

Let's hope that fixes it. If not, I guess a full re-install of OS + lxc's (via ansible) is up next.
