Thanks to Raphael for pointing me at the above bugzilla URL!

Yannick,

Would you be willing to try your test again after applying the
patch in http://lkml.org/lkml/2008/2/2/11 and rebuilding your
kernel?

This patch does not appear to be in 2.6.25-rc3.  :-(

I am reposting this patch separately.

							Thanx, Paul
