Public bug reported:
Sometimes, dns lookups via local bridge and local pdnsd take a long
time. Additionally, pinging a KVM machine attached via tap device to the
local bridge gives a "network unreachable" error because arp requests
don't get propagated to the VM. After some time and/or tcpdump starts
the problem goes away without any further modifications/help.
A downgrade to kernel 3.0.22 helps.
Kernels 3.1.x and 3.2.x seem to be a mess. Going live with them for the
next five years, seems rather questionable.
