The reason I keep posting my kgdb results is that I want to see if someone has experienced something similar. So far, I have had two crashes where I had saved the vmcore for debugging, and these two crashes are not identical. In fact, the only thing they have in common is that they are somehow related to networking. Also, I have no extra hardware. And I have tried the regular debugging stuff - After all, this has been going on for several months now, and I'm not the type of person who wouldn't notice that something is wrong with his beloved server. Sincerely, Daniel.
