Ah. That's because of this:

/proc/sys/sunrpc/rpc_debug: No such file or directory

Looks like I'll need to recompile with CONFIG_SUNRPC_DEBUG to do that. I
have a stable kernel upgrade coming up anyway: I'll get that done and
see if the problem recurs after the usual round-the-houses reboot...
with my luck, it'll go away :/
