Subject: 2.6.38 dev_watchdog WARNING
Date: Tue, 19 Apr 2011 11:40:02 -0600 [thread overview]
Message-ID: <4DADC8F2.9050700@canonical.com> (raw)
I'm seeing a lot of these kinds of bugs: WARNING: at
/build/buildd/linux-2.6.38/net/sched/sch_generic.c:256
dev_watchdog+0x213/0x220()
The kernel is 2.6.38.2 plus Ubuntu cruft.
A spot check of the 200+ hits on this string indicates they are
primarily due to these drivers:
ipheth
atl1c
sis900
r8169
As far as I can tell the warning happens when link is down on the media
(and has never been link UP) and are sent a transmit packet which never
completes. Is there a net/core or net/sched requirement to which these
drivers do not conform ? Are they not correctly indicating link status?
