Assertion failed - would be interesting to see the line number + having 
more information.

Usually, this happens:
 a) not enough resources configured (in this case, however, creation 
already should
     have failed and you wouldn't have gotten that far.
 b) called from wrong environment (from ISR or not from a task). From 
where and
     how do you call nfsInit() ?
 c) side-effect of general corruption.

You can change the 'MU_LOCK()' macro in rpciod.c from

assert( condition )

to retrieve the return value of rtems_semaphore_obtain() and
print it on failure (use 'printk()').
