Apparently the steps outlined in the bug worked in 2.6.35, and broke somewhere before 2.6.38.6. I can confirm the steps fail on a 3.0 based kernel and I'm trying to do a git bisect to find the commit involved, but I thought I would send this along to see if anyone might have an idea. (Also, I'm not really sure how valid of a usecase this was to begin with.) [1] https://bugzilla.redhat.com/show_bug.cgi?id=739534 josh
