Message-ID: <CA+Y=x3=jSrEaYdnaAF75p0utQq02MhoSh4SkshRVSc7JjjVPOw@mail.gmail.com> Date: Sat, 18 Aug 2012 16:40:18 +1000 From: Andrew Worsley <amworsley@...il.com> To: "David S. Miller" <davem@...emloft.net>, Alexey Kuznetsov <kuznet@....inr.ac.ru>, James Morris <jmorris@...ei.org> Cc: netdev@...r.kernel.org Subject: network packet corruption in v3.6.0-rc1 (and also in v3.5) Some times I get a burst of errors and dropped tcp connections with this warning. I had a similar issue with v3.5 (in fact v3.5 was unusable for https connections which would give bad MAC code messages at the application level).. The issue seems better under v3.6-rc1 where as it was very bad under v3.5. Let me know if there is something I can do to avoid this problem. I am using the USB r8712u wireless NIC if that is relevant as I haven't been able to get the native wireless working under the MAC book yet (requires proprietary firmware extraction which I am not familiar with) Much obliged if there is anything I can do to avoid it as it is rather annoying. Doesn't happen at all with my Debian wheezy 3.2.0-2-amd64 kernel.
