Default Bug#597489: Further information

I was able to reproduce the problem:

if I copy several GBs of small files over nfs to the machine it
eventually hangs kswapd eating up all CPU of one core.

This machine is not under any kind of heavy workload, it is just using
its RAM for caching.

Let me know if you need any more info.
