Hi!

Sometimes I get a strange behavior from the clock
It starts speeding up and seconds pass like miliseconds!!!
What could that be?
I have to reboot the machine to get things normal again.
thanks.
More on this:

* Keypresses are also afected! a quick press on a key produces lots of 
the same key - keyrate increased?

* Jumping cursor from kde's feedback jumps extremely quick!

* The same for the Input cursor

What could that be?

- Interrupts happens much faster than required?
- cmos clock goes mad?
