Description gryphon 2000-05-13 04:00:00 UTC

Using the 3Com ethernet port on a Dell XPi Latitude docking station.
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.

Does this problem still occur in newer versions of FreeBSD, 
such as 4.3-RELEASE?

I no longer have this hardware, so cannot test on a later release.

The originator is unable to confirm whether this is still a problem 
in newer version of FreeBSD.  If this is still a bug a new PR with 
more detailed information should be opened.
