Trying to mount 172.17.1.101:/mnt/disk1 on /mnt

assertion "RTEMS_SUCCESSFUL == rtems_semaphore_obtain( (llock),
RTEMS_WAIT, RTE3

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()').
