Package: linux-2.6
Version: 2.6.26-21lenny4
Severity: normal

On some of my systems, some time after boot (from about 1 to 8 days)
the kernel stops emitting packets (?). Using tcpdump on eth0 on the
guest I could see incoming ARP requests from the host but no answers.
No errors have been logged by the kernel and removing and loading again
virtio_net fixed the issue.

I experienced this bug 4 times, three on a system running 2.6.26-2-amd64
and one on another system running 2.6.26-2-openvz-amd64.
I have over 100 guests running the same kernels (some also running the
same services of the affected ones) but so far I have seen this only on
these two recently installed systems.
I can't see how this could be related but all the affected systems use
AMD CPUs, while most other systems use Intel CPUs.

The hosts are running RHEL5 (kernel 2.6.18-194.el5).

I'm assuming that's version 2.6.32-35@bpo50+1, therefore closing
with the corresponding version from squeze.

By the way, backports is now way out of date with security fixes.
