[Xen-devel] Network / e100 problems w/ 2.6.11-1.1284_FC4 dom0

[Klaus Wuerflinger <kwuerfl@xxxxxxxxx>]

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?

Thanks,
Klaus
