Running 2.6.8.1 and got a nice Oops from zebra (quagga).
After this, nothing routing-related worked. traceroute went to unin-
terruptible sleep, ip route get printed nothing and hanged... Perhaps
it's worth having a look so potential bug doesn't get into 2.6.9?
I'm not subscribed on the list and used a temporary account to avoid
too much spam but I will receive the mails for a few weeks or so.
