"Check your mouse cable. If this only happens when you move your mouse in a certain way, fix the mouse cable or replace the mouse. Check your kernel and harddisk settings. This message can also happen when the mouse interrupt is delayed more than one half of a second. Make sure DMA is enabled for your harddrive and CD-ROM. Kill your ACPI/APM battery monitoring applet. Try disabling ACPI, frequency scaling. Make sure your time is ticking correctly, often with frequency scaling it gets unreliable. Even if you're using the ACPI PM Timer as a clock source - actually this often leads to the above problem.
