Plug both keyboard and mouse into the onboard ports as opposed to plugging
the mouse into the keyboard and the keyboard into the machine.

Not necessarily, it depends on how the OS is configuring the ACPI CPU
states. At the log prompt is a big CPU load and disk i/o spurt and it
might drain the system enough, but linux & windows access patterns don't
happend to draw enough juice at one point to cause the memory error.

Otherwise it must be a chipset config issue or a quirk in the controller
which would have to be debugged with the hardware in hand. Definitely not
a problem that would be debuggable over email.
