I've been doing some research and it look as if this is a known issue. There are very similar bugs already open, such as here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/472057
I do plan to get to the bottom of them, but it will take some time. I have build some new kernels with new debug contained. These kernels enlarge the time out by quite a bit. Can you give them a go and report back your entire /var/log/kern.log please? http://people.canonical.com/~ljones/lp535315-netdev-watchdog-maverick/ -- WARNING: at /build/buildd/linux-2.6.32/net/sched/sch_generic.c:261 dev_watchdog+0x262/0x270() https://bugs.launchpad.net/bugs/535315 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
