Has anybody experienced >similar problems? There were several bugs in the if_de driver that were fixed in post-2.0R. The changes to all of the ethernet drivers are significant enough that porting a current driver back into 2.0R would be difficult. The only easy remedies I can think of would be to install the next snapshot (due out RSN), or use a different ethernet card (like an SMC 8416) until 2.1R is available. -DG
