I'm running a PE6600 with 16GB of RAM with RH8.0. With this setup it is
quite easy to trigger a VM problem by simply copying a large amount of
data. In this state the 2.4.18 kernel can go from slow to unusable quite
The 2.4.20 kernel from the RH beta improves things. We still get a
slowdown but the system can be recovered.
