While running a NFS server on a ext3 filesystem (selinux kernel gentoo-dev-sources 2.6.1-gentoo) the attached kernel opps was generated.
On the client machine I had the entire portage tree mount (/usr/portage) with options (noatime). Server export options were (rw,no_root_squash,sync)
I was undertakeing a "env ACCEPT_KEYWORDS="~x86" emerge -pvuUD world" on the client machine when the crash occured.
nfs-util-1.0.6 on client and server.

Changed to UPSTREAM - will reopen/give more details from the upstream devs as they become available.
The following patched fixed the problem. This has been applied to the 2.6.4 kernel. Thanks to the kernel devs for their help.
