Short: 36 Nehalem nodes available again now.

Longer: After the first round of rebooting and simple troubleshooting,
we have 28 nodes with various types of errors to take care of. As this
hardware generation packages four nodes into each chassis, and we need
to have the whole chassis down for hardware work, those 28 nodes also
block a number of neighbouring nodes. We got 9 chassis with all four
nodes working, which makes for 36 nodes available at the moment.

We will continue troubleshooting and casing nodes for service tomorrow.
