asterisk users - Sep 2003 - "i8253 counter to high. Resetting..." message

Hi,

I have one * box with this message repeating endless in the system console.
It dissapear after a system reset, but it is back after a while.

The only PCI card installed is a X100P.
It can be related to Asterisk and/or X100P card driver or it is a system
failure?
The system is a Celeron@1.3GBHz, original Intel Motherboard with RH9.

Thanks,
Dan
