That's really odd.

with your .config and !CONFIG_PNFSD
and with no modules configured
though with modules enabled:
CONFIG_MODULES=y
# CONFIG_MODULE_FORCE_LOAD is not set
CONFIG_MODULE_UNLOAD=y
# CONFIG_MODULE_FORCE_UNLOAD is not set
# CONFIG_MODVERSIONS is not set
# CONFIG_MODULE_SRCVERSION_ALL is not set

when turning on rpc debugging I see the server rejecting
I believe the EXCHANGE_ID RPC on BADCRED:

svc: svc_authenticate (1)
svc: authentication failed (1)

I see this also over NFSv4.0...

Is this what you're seeing too?
