I am also seeing disconnects with the atl1c under load. There is a related kernel bug: https://bugzilla.kernel.org/show_bug.cgi?id=54021
Problem should be fixed on lasted git: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/net/ethernet/atheros/atl1c?id=7b70176421993866e616f1cbc4d0dd4054f1bf78 Please consider applying this patch to your kernel, since lan is not usable with this bug. I am using kubuntu raring 64bit. ** Bug watch added: Linux Kernel Bug Tracker #54021 http://bugzilla.kernel.org/show_bug.cgi?id=54021 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1036668 Title: atl1c: network get stuck randomly under high load Status in “linux” package in Ubuntu: Incomplete Bug description: Hi, since a few days I am using a FreeNAS server as home storage, and I noticed that often when I am trasferring large ISO via NFS, the network stop transmitting and receiving packets: I cannot ping any other host on the local network, and the system doesn't recognize even the unplugging of the ethernet cable (I tried to change switch port). In the dmesg there isn't any error, but the unique way I've found to recover from this situation is to reload the kernel module.
