If it is, it goes further back than 2.6.31 as that bug report suggests. I was
able to reproduce it once in v2.6.30 as tagged, and am still laboring to find
an A-B point to bisect. Failure rate is significantly lower in 2.6.30, but
it did happen once.

So far, Ubuntu linux-image-ec2 (2.6.32-30{5,7}-ec2), our 2.6.32.12, vanilla
2.6.31, and vanilla 2.6.30 have demonstrated this issue in my testing
environment.  All x86_64.  I am unable to reproduce on i386 to this point.
