Subject: Hang when testing with AMD64 with Tg3
Date: Mon, 04 Oct 2004 17:11:11 -0700 [thread overview]
Message-ID: <1096935071.22155.6.camel@localhost.localdomain> (raw)
Doing simple iperf test on new opteron with tg3 against existing Xeon
system. I am seeing something wierd, the connection hangs right away.
Is this a TSO bug.
Sender: BK latest (2.6.9-rc3) Tg3 (XX.YY.250.3)
Receiver: BK + netdev(jeffm) + dave's latest e100 (XX.YY.1.73)
Both machines are directly connected with a netgear 100mbit switch.
