Gnu cp not working on partition mounted witth acls flag set

When I use gcp -pR to recursively copy a directory to another, there always is an error:
Code:
preserving permissions for `xxxx': Invalid argument

Later I find such kinds of problems only occur on the partition mounted with acls flag set.

I want to ask if it is the gcp that cannot work with the access control list of FreeBSD, or is it probably a bug?
