From mii-tools -w XXX I can see, that link is going up and down every 3-8 seconds. Take down/up interface doesnt help. However there is no any error in dmesg or anywhere else. Tested kernel is not modular, only reboot helped. NIC details are: driver=tg3 driverversion=3.137 firmware=5720-v1.39 NCSI v1.5.1.0 Best regards -- Tomas Charvat Excello s.r.o.
