Realtek, and many of those running the tulip drivers with non DEC chips can be really flakey. If you're looking for inexpensive, high quality NICs, the 3COM 3c905 series are often available for about $10US.

Re: Linux server packet loss - stopped occassionally
For my use I love the realteks, not a problem with them. For business use when doing jobs I tend to use 3com 509's, same with modems, give me a good old 3com anytime.
