Everything is fine with a eepro100 on the 64x2 box that gave the same
problem with a nVidia Corporation MCP51 Ethernet Controller (rev a1)
using the forcedeth module. On the x86_64 laptop the problem is with a
Broadcom NetXtreme BCM5788 using the tg3 module. Switching back to a
2.6.18.2 kernel, there is no problem.
With all configurations of cards on both, route -n is the same on all
kernels and instantly reports back. With >=2.6.19 on the laptop, netstat
-r takes a very long time before returning the information ~30 seconds,
instantly on 2.6.18.2.
This could be a problem with DNS. Could you do all tests
(including pinging) with -n option?
I've read your other message on netdev and see you
have firewall working and addresses from various
networks in logs. I think it would be much easier
to exclude possible network config errors and try
to isolate pinging problems by connecting (with
switch or even crossed cable if possible) only 2
boxes with firewalls and other net devices disabled
and try to repeat this pinging with tcpdumps.

It seems >=2.6.19 and the SuSEfirewall are incompatible.
Turning off the firewall on the laptop cured the problem using
2.6.20-rc2 and 2.6.20-rc3. I thought it was off. On the 64x2 box, the
firewall is turned off, so I shall have to reconfigure the network to
use the Gigabit ethernet instead of the eepro100 in case I turned it off
after seeing the bug on that box, but didn't stop the firewall.
There is still the problem where the ethernet doesn't get configured
with acpi=off which I shall post to the acpi devel list, but this is not
a showstopper for me. ifconfig eth0 192.168.10.5 returns SIOCSIFFLAGS:
Function not implemented.
Thanks and Regards
Sid.
