[Xen-devel] Network / e100 problems w/ 2.6.11-1.1284_FC4 dom0
Hi, has anyone lately experienced problems with the network stack of the dom0 kernel 2.6.11-1.1284_FC4 (also 1.1267, 1.1276)? I''m using synergy user space app. in dom0, using e100.ko NIC driver. synergy sends very small packets on a TCP connection for every mousemove or keyboard press. After a couple of minutes or sometimes hours, the connection suddenly "dies", ie send-Q of dom0 for this connection increases (netstat output), client does not receive any data. tcpdump shows that broken packets are sent to the link (funny things like "TCP checksum mismatch" and "invalid packet length"). This behaviour does not appear if I boot default FC4t2 kernel! Any hints?
