The original poster (Jeff) should have mentioned that is is a build bug problem in
Linux 3.5.4.  Jeff, have you tried 3.5.7?  I expect that this problem is already
fixed, if not in 3.5.x then in some later kernel version.

Jeff, also please provide the kernel .config file as an attachment here since
the one posted in the forum does not download (or has been deleted).
