Wolfgang,
Same issues here. I'm sure my problem is related to the intel ethernet
device (module e1000) under stress. My system is a ibm/lenovo x60s.
My sympton is instant system freeze when ethernet card is under stress. The
message from the NMI is:
NMI received for unknown reason a0 on CPU 0
By doing a tcpdump i checked there's a problem in the LAN, as I saw
34000 packets of this type in just 12 sec of tcpdump:
21:51:01.531747 arp who-has 192.168.1.1 tell 192.168.1.1
The system works stable for weeks. When I connect the sytem to the
network in this state between 10secs and 10min the system freezes..
Regards,
Valentino
