After last update from kernel version 4.4.0-176-generic to 4.4.0-177-generic my machine which does repository mirrors on NFS filesystem hung.
After hang the system is pingable, and all processes run well until they need to perform IO operation. Then they end in 'D' state.
If dmesg -w -H is run prior to hang you could get following report:
