WARNING: at /build/buildd/linux-2.6.31/net/sched/sch_generic.c:246 dev_watchdog+0x1f6/0x210()

Hope the attached is relevant...

Omg, a monkey went crazy and marked many bugs duplicates of this one, although they're not remotely connected.

I have this warning in my kern.log at every boot.

Everything works except :

- I frequently have no window manager and even sometimes no panel at startup (under Xfce)

- I sometimes have network issues :
PING 80.67.169.12 (80.67.169.12) 56(84) bytes of data.
From 192.168.1.1 icmp_seq=1 Destination Net Unreachable
From 192.168.1.1 icmp_seq=2 Destination Net Unreachable
From 192.168.1.1 icmp_seq=3 Destination Net Unreachable
From 192.168.1.1 icmp_seq=4 Destination Net Unreachable
I suspect the router or the ISP to be responsible for this, since I can reach the router.
Besides, rebooting the router once or twice does the trick.

Don't know if any of these issues is linked with the warning.

BTW, I haven't found this error anymore which I got from plugging my
HTC G1 into the computer, to automatically get a new network
interface. The computer had USB1-ports and I was running from livecd.
I actually think the kernel update did the trick. But I haven't used
that computer in a long time now, -- but afaik, it worked after kernel
update.

Sorry, after recheck, it does not happen to me every boot. It is not linked to my window manager error. I'll try to correlate it with the network issue.

I think I don't have this problem anymore.... :)) thank you

Can anyone experiencing this on the latest Lucid available at cdimage.ubuntu.com please provide me with apport collected data to this bug?

Taras,
    I am also interested to know if you are seeing these oopses anymore. we have pulled in a number of patches and I am under the impression that the issue should be resolved.

Thanks!

~JFo

haven't seen this oops in a long time.

count my vote as "resolved".

Neither did I. Resolved here as well.

Jerome / shigeo,
     Thanks for your update. I am going to go ahead and mark this a Fix Released. Should anyone continue to encounter this, it is an easy thing to reopen and supply apport logging.

Thanks!

~JFo

Jeremy,

Have not experienced the issue since I posted the bug.
