The simplest explanation is that you have both cards plugged in and they are
confusing each other when you are getting broadcast messages.

well, only the e1000 is "plugged in", the marvell chip is on the main board...

By plugged in I mean plugged in to the Ethernet. Not plugged into the system
bus. Make sure only one card is on the ethernet at a time.

Basically a martian packet is a packet that comes in but Linux wasn't
expecting
that interface to get it.

Otherwise, if both cards aren't plugged in something else on your network is
misconfigured.

any suggestions what to check or test ?
it's a plain dump 100mbit switch with 2 PCs connected (the test PC with 11.3
and two nics, and the server which I use to probe running 11.1 with e100).

Start by making sure only one NIC is plugged into the Ethernet for this
machine. Then you will want to check the route tables and IPs of the machines
on the network using the ifconfig, netstat and arp commands I gave below.

The warnings are harmless and can be ignored or disabled via
/etc/sysctl.conf
net.ipv4.conf.all.log_martians = 0.

at the first boot these "warnings" haven't been completely harmless as ping
did
not work at all (neither did ssh) but instead I got those messages for eveyr
ping package being received!

disabling those warnings likely won't make the ping work suddenly I guess ?!

What does /sbin/ifconfig, netstat -nr and arp read when these things happen?

I'll check when it completely blocks for the next time...

Alright, leaving NEEDINFO on you to gather this information.
