Description François Valenduc 2010-06-13 15:12:17 UTC
With 2.6.35-rc3, nfsd hangs at startup. A git-bisect run shows that the first bad commit is the following:

commit 597a264b1a9c7e36d1728f677c66c5c1f7e3b837
Author: John Fastabend <john.r.fastabend@intel.com>
Date:   Thu Jun 3 09:30:11 2010 +0000

    net: deliver skbs on inactive slaves to exact matches

Indeed, if I revert it, the problem doesn't occur. Looking at the description of this commit, I should probably add that I use a virtual tap interface and a bridge for running a kvm machine.
