D means device driver. The process is suspended while it waits for a system call of some sort to finish, often a read() or write(). It's unkillable in this state.
lockd is part of the kernel, not truly a process. I think it's part of the kernel system that handles nfs. The message about lockd you see is related to NFS problems.
Maybe this will help you:
Debian User Forums • View topic - kernel: lockd: cannot monitor
Anyway, NFS is a very elderly protocol by now and has a few unsolvable flaws, you might consider alternatives like CIFS.

LAPTOP_MODE(8) System Manager's Manual LAPTOP_MODE(8)
NAME
/usr/sbin/laptop_mode - apply laptop mode settings
SYNOPSIS
/usr/sbin/laptop_mode [ cmd ] [ force ]
DESCRIPTION
This manual page documents briefly the /usr/sbin/laptop_mode command. laptop_mode is a program that applies the settings given in the
/etc/laptop-mode/laptop-mode.conf configuration file. The primary use is to control the laptop mode feature included in Linux kernels with
versions 2.6.6 and higher, and 2.4.23 and higher. This feature increases battery life by letting your hard drive spin down. This is
achieved by grouping disk write activity into "chunks" that are spaced at larger intervals than they normally would be. In addition to sup-
porting the Linux kernel's laptop mode feature, /usr/sbin/laptop_mode also supports various power saving modules which are configured
through configuration files in the /etc/laptop-mode/conf.d directory.
It is not recommended to call /usr/sbin/laptop_mode directly to start or stop laptop mode, except in hardware event handlers. To apply new
configuration settings from laptop-mode.conf, call the laptop-mode service init script with the reload parameter.
COMMANDS
Specify force as the second parameter to force laptop_mode to re-apply a state even if the computer is already in that state. These are the
values that are allowed for cmd :
auto Enable or disable laptop mode based on the current power state. Note that this will not do anything if the laptop-mode service
has not been started!
status Display a status report about everything that laptop_mode affects.
