-Warning: you must disable syslogd before you do this, or you must
-make sure that kernel output is not logged.
+The command sets a sysctl to cause the kernel to log all disk
+writes. Please notice that there is a lot of data. So please
+disable syslogd/syslog-ng before you do this, or you must make
+sure that kernel output is not logged.
When you're done, disable block dump using:
# echo 0 > /proc/sys/vm/block_dump
Alternative:
laptop-mode-tools provides a tool named lm-profiler (laptop mode profiler)
which handles block_dump on its own.

Display stats about memory allocations performed by a program:
Usage example for 'ls':
* If you change the time (using 'date --set ...', ntpdate,...)
it is worth setting also the hardware clock to the correct time:
- # hwclock --hctosys [--utc]
+ # hwclock --systohc [--utc]
Remember to add the --utc -option if the hardware clock is set
to UTC!
