Any progress on this? Linus' latest kernel (2.6.37-rc5-git3) still has
the problem. And this is a regression, so I don't think you can just
ignore it.

Is there a bug opened to track this bug already? I couldn't find one on
bugzilla.kernel.org, but maybe I missed it. If there is none, I'll
create one.
