Everything seems to work fine tho... just error poping out every few minutes. Its kinda random, sometimes time between is ~5min, sometimes 30sec... If i boot with old kernel (3.15.8) this error is gone. If you need anything else i can provide config etc, but since this seems like somekind of trace i tought its enough :)
Can you post that summary to netdev@vger.kernel.org
yeh i did... also more similar errors for other people. https://lists.debian.org/debian-kernel/2014/09/msg00362.html http://www.stben.net/cgi-bin/engdnews/dnewsweb?cmd=article&group=linux.debian.kernel&item=30305&utag= maybe even this? https://bugzilla.redhat.com/show_bug.cgi?id=1148612
This seems to be fixed in 3.18rc1.
