Nothing is broken, you don't have to do anything. A page fault is a normal activity in a modern OS. Solaris calls them "major" if a disk access is needed.

lm-profiler
LM-PROFILER(8) System Manager's Manual LM-PROFILER(8)
NAME
/usr/sbin/lm-profiler - laptop mode profiler
SYNOPSIS
/usr/sbin/lm-profiler
DESCRIPTION
This manual page documents briefly the /usr/sbin/lm-profiler command. lm-profiler is a tool for profiling disk operations. It is a part of
laptop mode tools and is useful only in relation to rest of laptop mode tools. It helps you to detect programs and services that use up
system resources and that cause disk activity, and it allows you to disable them when laptop mode is active.
When you start lm-profiler, it will execute a "profiling run", which can take some time. Start lm-profiler when you are working on batter-
ies, preferably, because that will allow it to analyze the actual situation that it is supposed to optimize. During the profiling run, you
can use your system normally; however, any disk activity caused by your actions will end up in the profiler's results. When the profiling
run is finished, you will be presented with a list of programs that deserve your attention, either because they listen on a network (which
is not usually useful when you are working offline) or because they caused disk activity in a disk-spindown-unfriendly pattern. When lm-
profiler can guess an init script that belongs to a program, it presents you with the opportunity to disable the program when you are work-
ing on battery. It does this by placing a link to the init script in /etc/laptop-mode/batt-stop. Any programs that lm-profiler cannot find
an init script for is simply reported, so that you can stop the program manually if you want to.
WARNING ABOUT DISABLING PROGRAMS: It may not be safe to disable some programs. They may be needed for proper operation of your system. Dis-
able services only if you know what they do and why you don't need them.
FILES
/etc/lm-profiler.conf
lm-profiler retrieves its profiling rules from this file.
