I've seen similar bootup issues.. but the nfs lock service failure
isnt the problem afaict. Its most likely related to a service that is
starting on your system after the nfslock service runs.  I was able to
get past my bootup problems by trial and error disabling services one
at a time, until I could get a full bootup working again.
try to boot into runlevel 3 and see how far it gets
reboot into runlevel 1 and disable the service next in the list after
the last message seen
reboot into runlevel 3 and see how far it gets.....
on and on till you get all the way into the system.

I had to do this repeatedly and it appears that multiple services were
causing bootup problems for me.I have NOT disabled the nfslock service
as part of my troubleshooting effort.
my nfslock service still boots with a failure, but I can now boot
after disabling a number of other services.  I still need to go back
and try to reproduce the problem by re-enabling services that I turned
off.  Here is the list of services I turned off, some of these might
not be a problem I still need to go back and try to reproduce the
bootup errors with each package to be sure:
