Neither your code, nor your setup is wrong, the error come from vxworks
uvm. Printing uvm_irqlock shows that the interrupts got disabled
somehow.

UVM and vxworks are separated skins, that require incompatible timer
setting. Since you are using UVM (I guess), select only uvm in kernel
configuration, or select vxworks skin as a module that you do not load
when running applications using the UVM skin.
If you feel lucky, the 3rd option coming with v2.2 is to get rid of the
UVM and use the new direct call interface now available from user-space
for the VxWorks skin. In such a case, you need 1) the development
trunk/, 2) to load xeno_vxworks, 3) work with the new VxWorks interface
from user-space exactely the way one would use the existing native or
POSIX skin.
