I've been using it for about 48 hours now at 100Mbit doing copies of
filesystems with several rsync commands in batch mode (one after the
other). There have been no "rock-solid" hangs like with the old tg3
driver. Here are the lines from dmesg to confirm I'm using the correct

tg3.c:v1.2 (Nov 14, 2002)
divert: allocating divert_blk for eth0
eth0: Tigon3 [partno(BCM95700A6) rev 7104 PHY(5411)] (PCI:66MHz:64-bit) 10/100/1000BaseT Ethernet 00:06:5b:0e:af:0f
divert: allocating divert_blk for eth1
eth1: Tigon3 [partno(BCM95700A6) rev 7104 PHY(5411)] (PCI:66MHz:64-bit) 10/100/1000BaseT Ethernet 00:06:5b:0e:af:10
tg3: eth0: Link is up at 100 Mbps, full duplex.
tg3: eth0: Flow control is off for TX and off for RX.

That said, I'm still experiencing system slow-downs as my rsync's
progress. After about 2 hours, the system is noticeably slower interactively
at the shell. The load reported by top is a mere 2-3. As time goes on
it gets much slower and the load grows. More and more time seems to be
spent in "system time".

I reported this in another thread called "The system takes over". This
happened under the bcm5700 driver as well so it may have nothing to do
with the network driver.  I'm still looking at this trying to isolate
the problem a bit more.
