it could look like this. $ cat /etc/network/if-up.d/bug-1200243 #!/bin/sh [ "$IFACE" = "eth0" ] || exit 0 kver=$(uname -r) case "$kver" in 3.10.0-3*) :;; *) exit 0;; esac echo "BUG 1200243 workaround: ethtool -K eth0 sg off" | logger ethtool -K eth0 sg off $ chmod 755 /etc/network/if-up.d/bug-1200243 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1200243 Title: Network lock up Windows Azure/Hyper-V Status in “linux” package in Ubuntu: Triaged Status in Gentoo Linux: New Bug description: Netwokring on Windows Azure 13.10 instance just lock up.
