I don't really see any deadlock here... hmm. Tejun, do you see anything
wrong with the "locking" in workq stuff here?
Something is holding the RTNL, and a bunch of other things are trying to
acquire it. We don't really know who's holding it and who's acquiring it
though.
I notice that the system is consistently running OOM, even though
it has 2GB RAM. I'll try disabling some of the memory-poisoning debugging that may
be consuming excess amounts of RAM to see if that helps any.
