close it until the problem is fixed in the mainline.
Comment 1 Ben Greear 2011-05-04 23:30:43 UTC 
Root cause appears to be the slub cmpxcg issue recently fixed in
2.6.39-rc6+.  I was compiling my kernel for 586, so was susceptible,
even though processor was much more recent (Atom).

Please feel free to close this bug.
