What devices are connected to your system?
Perhaps a Linux driver, for a device is having problems. Perhaps a device is generating lots of interrupts.
In the case of a continual interrupt storm the kernel will detect and log it (and take some attempt at avoiding action).
Can you disconnect any devices and see if the slowness goes away?
Easier to look in /proc/interrupts for stuff going at crazy rates
