Hi, Dave,

Thanks for reporting this. I sent out a patch to fix this problem
(suggested by Nick Piggin). The patch is available at

http://lkml.org/lkml/2007/9/12/113

Could you try the patch and check if the problem goes away?

Any pointers on how to reproduce the problem would be extremely useful.
