I was to fast with this statement. Because although even the
manufacturer expected a hardware issue and replaced the motherboard on
warranty, the issue appeared again with the new motherboard.
We're currently tracking it down to what causes the oopses and
freezes. It currently seems to be a NFS related issue. If we stop our
NFS mount tests (it's a monitoring server), the machine seems to be
stable. If we reenable it, it only takes hours to the next crash.
Also interesting is that after the Oopses happened, the system was
still usable for another 1.5 minutes or so and only then froze. So
after the following Oops today, I even could log in via ssh, but when
before I managed to type "uptime", the machine was frozen.
