Sysinstall reads this as using the "ep0" defice, which works fine on 3.x kernels. However, when using the 4.0-Release kernel, the ethernet driver is unworkably slow. Traceroute and netstat show the interface and other hosts on the same subnet, but ping usually just hangs (times out). On the few cases where ping does return a results, the result is always multi-second, cycling down with a pattern of: 7070ms, 6060ms, 5050ms, 4040ms, 3030ms, 2020ms, 1010ms -- then hangs. However, the same hardware and network (and config) works consistently and cleanly using either the 3.2 or 3.4 kernels. >How-To-Repeat: The hang (packet time-out) is consistent. The few times the packets return are sporadic. >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
