Hi - Have you tried opening the box and making sure all the connectors,
cards, etc. are well seated. The last couple times I have dealt with a
really erratic Linux box, this was the problem. I once experienced
problems somewhat similar to what you mention on a box that had a SIMM
that was not seated just right. Popped the RAM out, put it back in and
the problems went away.
