I initially didn't think it was networking related, but the it seems to be (weakly) correlated with network activity, and there was IPv6 stuff in one of the backtraces, so I've reassigned to the networking component. However, I'm not sure if that generates an email to netdev. Could anyone please have a look? https://bugzilla.kernel.org/show_bug.cgi?id=102291 /* Steinar */ -- Homepage: http://www.sesse.net/
