This looks a lot like Dan Kavan's problem,
http://archives.postgresql.org/pgsql-admin/2006-09/msg00092.php
which we have now pretty well proven was a kernel bug.

2.6.5 what exactly?  And what's the "Intel platform"?  Although I don't
have any details about the kernel bug, I can't help suspecting that it
only manifested on systems pretty similar to Dan's dual Opteron.
