I saw in the de0 driver that it prints out diagnostics when compiled with DIAGNOSTIC, so I tried that. These are the errors I see on the console: Aug 27 22:30:32 terminus /kernel: de0: receive: 00:20:e0:0c:38:59: alignment error Aug 27 22:30:33 terminus /kernel: de0: receive: 00:20:e0:0c:38:59: bad crc Aug 27 22:30:33 terminus /kernel: de0: receive: 00:20:e0:0c:38:59: alignment error Aug 27 22:30:35 terminus /kernel: de0: receive: 00:20:e0:0c:38:59: alignment error Aug 27 22:30:36 terminus /kernel: de0: receive: 00:20:e0:0c:38:59: bad crc Aug 27 22:30:36 terminus /kernel: de0: receive: 00:20:e0:0c:38:59: alignment error Aug 27 22:30:37 terminus /kernel: de0: receive: 00:20:e0:0c:38:59: bad crc So, what could cause this? Is this bad hardware, a driver problem, or what? Please, any help appreciated. Thanks, Ben
