Subject: sch_generic warn_on (timed out)
Date: Mon, 11 Jul 2011 16:48:34 -0400	[thread overview]
Message-ID: <20110711204834.GA4950@redhat.com> (raw)

We've recieved quite a few bug reports in Fedora recently concerning this warning in
sch_generic..

            WARN_ONCE(1, KERN_INFO "NETDEV WATCHDOG: %s (%s): transmit queue %u timed out\n",
                      dev->name, netdev_drivername(dev, drivername, 64), i);

https://bugzilla.redhat.com/show_bug.cgi?id=702723 is our 'master bug' that we're
duping all others against. It seems to be showing up on a variety of different
hardware (r8169, atl1c, ipheth, e1000e, 8139too). Do all these drivers need
fixing ? or is it just 'crap hardware' ?

note that I've only been looking through fedora 15 bugs so far (which is still on 2.6.38),
but looking at the commit log for sch_generic, it doesn't seem that there's anything
obvious that needs backporting.

thanks,

	Dave
