Message-ID: <AANLkTikJJ3dJ-Oy7iOMz=JU-9HvATeH1Ntt2VqZPwpGM@mail.gmail.com> Date: Fri, 11 Feb 2011 16:48:10 -0200 From: "Leonardo L. P. da Mata" <barroca@...il.com> To: Guo-Fu Tseng <cooldavid@...ldavid.org> Cc: linux-kernel@...r.kernel.org, netdev@...r.kernel.org Subject: Re: jme driver loses connection after resuming from suspend Hello Guo-Fu Tseng, not good news, the patch is not working. But i've noticed one interesting behavior. I've done 2 tests, on the first i've suspended, resumed and after resume done a tcpdump. Only after the tcpdump, the network starts to work. ethtool-before ethtool-before-d ethtool-after ethtool-after-d ethtool-after-tcpdump ethtool-after-tcpdump-d on the second test, i've done the tcpdump befor suspending, and after the resume the connection works. ethtool-before-2 ethtool-before-2-d ethtool-before-2-tcpdump ethtool-before-2-tcpdump-d ethtool-after-2-tcpdump ethtool-after-2-tcpdump-d I've attached the ethtool logs, and they are listed in the order of the steps. i hope we can solve this mistery.
