Message-ID: <20120802133200.20698.qmail@science.horizon.com> Date: 2 Aug 2012 09:32:00 -0400 From: "George Spelvin" <linux@...izon.com> To: romieu@...zoreil.com Cc: linux@...izon.com, netdev@...r.kernel.org Subject: Re: v3.5: NETDEV WATCHDOG: eth0 (r8169): transmit queue 0 timed out My, that was exciting. I rebooted with the drastic timeout reduction I proposed last night. (Actuallly, I compiled a version before I realized TSO could increase the output size, so it was set to (HZ/150) = 2 jiffies.) Anyway, it worked fine last night, and *didn't* display the NETDEV WATCHDOG warning on reboot. But this morning at uptime 12 hours, (and as the office was filling up in the morning, although there certainly was *some* traffic overnight), things went pear-shaped: Aug 2 12:45:11: ------------[
