Greetings friends,
I have been experiencing a number of networking issues with three new
machines I have purchased. They are Dell SC1425 machines, each with two
64-bit processors. I have attached the dmesg log to this email for your
review.
The symptom is simply that every once and a while the machine appears to
go off line. I can ping it and it responds, but I cannot SSH into it or
generally get any other type of network access to it. This happened a
few times and so I turned kernel logging on in the hopes that I could
catch some debugging information. Here's what I found this morning
(after the machine went down). In order to restart the machine I had to
pull the plug. It would not respond to the three-fingered salute or to
the power button.
