Joseph, thank you for your comment. I installed the kernel you pointed me:
3.9.0-030900-generic #201305071030 SMP Tue May 7 14:39:20 UTC 2013 i686 i686 i686 GNU/Linux rebooted and the reset doesn't appear anymore. Now I'm copying some large file over the network and it seems to work properly, so I can tell that the but is already solved by the upstream kernel. :-) ** Tags added: kernel-fixed-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1176577 Title: mei unexpected reset in kernel 3.8 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1176577/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
