I have quite a few i7505 (Supermicro X5DAL-RG2 - same as yours but with dual e1000 and SATA), and have not had any problems that could be attributed to ethernet, including a machine running with constant traffic over 500Mb/s on gigabit. Mostly inbound traffic though, but have not had any problems with any others either. Using 2.4.22. Do you get anything in the logs/serial console?
