There used to be, long ago, some problems with HZ=1000 which were
related to some diskless stuff -- now i forget the details but i
believe it was some timeout field or the like overflowing.
This was fixed years ago, though, and i believe the relevant
code was in /sys/nfs/bootp_subr.c and related ones.
I am running an NFS server with 4.5 and HZ=1000 (no device_polling though)
and it seems to work fine.
cheers
