One data point that I'm finding so far, is that it is easier to trigger
in 2.6.35.x than 2.6.32.x.  It also doesn't seem to be dependent on the
version of the host kernel.  I can reproduce it running 2.6.35.4 or
2.6.32.22.

If you want a small gentoo starting point, I have a 56M compressed
ext3 gentoo guest filesystem I can share with those who wish to test.
I don't want to make it available to everyone, due to size.
