Invalid cross-device link - Help...

I have the following environment and am running into the error message:
"svn: Can't move 'tmp.3' to .....: Invalid cross-device link"

svn, version 1.1.1 (r11581)

Linux 2.6.5-1.358 on i686

/dev/hda3 is /

/dev/hdb1 is /home

I log in as buildctl whose home is /home/buildctl

I checkout to my workspace

svn checkout -r HEAD svn://svn/repos/Duff/Main
"/BranchControllerZone2/BWS2" > /BranchControllerZone2/SCM_get.txt

I switch the workspace to a specific branch

switch -r HEAD svn://svn/repos/UserBranches/jwest/Duff/Main
"/BranchControllerZone2/BWS2" > /BranchControllerZone2/SCM_get.txt

I attempt to merge:

svn merge -r 14904:15192 svn://svn/repos/Duff/Main
"/BranchControllerZone2/BWS2" > /BranchControllerZone2/SCM_get.txt

I get the following Error:

svn: Move failed

svn: Can't move 'tmp.3' to
'/BranchControllerZone2/BWS2/src/Admin/SupportCenter/XSL/Brands/Connecte
d/.svn/tmp/text-base/PC.gif.svn-base': Invalid cross-device link

The workspace and my home directory are on different devices, Is this
why the problem is happening?
