I did # ifconfig eth0 <ip> netmask 255.255.255.248 mtu 750 up and was unable to reproduce the problem anymore. Then I retried with MTU=1500, and it would happen again every now and then. Then I tried 1000, 1400, 1450 and finally 1480 -- all of which seemed to work. Retried with 1500 -- hangs happened again. I've no set the MTU to 1480 (which I gather shouldn't impose great performance penalty), but I'm still baffled what is the actual problem. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
