What we mean by "Heavy load"

To test your kernel configuration on a new hardware, do the following actions all together:

• ping -f to_a_local_ip_address
• ping -f localhost
• top on a virtual terminal
• top on a X11 terminal or via remote terminal (SSH)
• while 'true'; do ls -lR / > list; done
• while 'true'; do cat /proc/interrupts; done
• long-time compilation, such as a new kernel, qt library etc

This is what we intend by heavy load.

If you are using X11, mix virtual terminals and console terminals (CTRL-ALT-F1 etc). If you are non using X11, mix console terminals (CTRL-ALT-F1 etc) and remote ones (via ssh, telnet etc)

Let your system work under this load for hours and while performing these tests try also switching console terminals randomly by pressing CTRL-ALT-F1, CTRL-ALT-F2, CTRL-ALT-F3 etc, plugging/unplugging USB devices etc.

Before starting your tests, remember also to disable SMI and load rtai_smi_rt module into your kernel:

insmod rtai_smi.ko
