Description:

I get a kernel oops (on 3.16.1-1-ARCH) when building with a directory on an NFS share using makepkg (related to an ACL call). This is a known problem upstream. It has also been patched by Fedora upstream among other distros.
Here is redhat's bugzilla page:
https://bugzilla.redhat.com/show_bug.cgi?id=1131551

Steps to reproduce:
Mount an nfsv3 share, makepkg on that share.

Here's the oops message in dmesg:
