Luis reported some problems, too (last October).  The discussion
trailed off waiting for him to look at it further.  I also tested on a
PowerPC system before committing the patch, so it's got to be some
combination of factors that didn't show up on my target.

Covering my ass out of the way, can you be a little more specific?
What CPU/kernel, any useful debug logs you have, et cetera.
