Title:
  NULL pointer deference in set_nfsv4_acl_one

Status in “nfs-utils” package in Ubuntu:
  New

Bug description:
  I can reliably reproduce an NFS BUG for set_nfsv4_acl_one by running
  `cp -a`. Both client and server are running in AWS EC2. The server
  mount is on EBS.  This error is new since upgrading our nfs server
  from natty to precise.
