Here's output from my machine with bge(4) NIC: Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll bge0 1500 <Link#1> 00:16:35:... 7808595 35 3451475 0 0 Uptime is 8 days, the machine is only moderately loaded, but gets quite some amount of NFS traffic (as a client). OS is FreeBSD 6.2-PRELELEASE as of October 19th. Whie 35 ierrs in 8 days isn't much, I think it still indicates a problem somewhere. It should really be 0. (I haven't experienced any freezes or other problems, though.) Maybe you should ask on the -stable mailing list for others with bge(4) NICs to check. It looks like a bug in the driver. Oh by the way, do you have polling enabled? Try to switch in on (if disabled) or off (if enabled) and check whether it improves the situation for you.
