It looks like that the following patch

was not included.  At least for kernel-2.6.8-1.520.

The above was posted by Jeff Garzik on lkml and that piece missing
was the reason for a "paper bag" 2.6.8.1 release.  Look for
a posting "[PATCH] Re: [2.6.8-rc4-bk] NFS oops on x86-64" from
13 Aug 2004 23:23:34 -0400 and a Linus comment "Ahh. Jeff posted the
right one, obviously".

Is a bugzilla ticket opened for this bug?  Curiously enough
I was not hit by that even when using NFS.
