This has been fixed in: http://git.kernel.org/cgit/linux/kernel/git/davem/net-next.git/commit/drivers/net/xen-netback/netback.c?id=59ae9fc67007da8b5aea7b0a31c3607745cfbfee and the patch has been included in 3.16.x, but I cannot find it in the current longterm releases. We have an open gentoo bug report about it: https://bugs.gentoo.org/show_bug.cgi?id=517852 This bug doesn't happen on all xen-dom0 machines, but I can confirm that on the problematic machine after applying the aforemention patch, the problem gone away and the system has been running for 60 days without problems. Please consider applying the patch to the longterm kernels. Thank you
