>Description:
The machine which is a dual PIII "locks up" after a day or so when it is compiled with an SMP kernel.  I have been unable to duplicate this with a UP kernel.  When I say lock up, the following things occur.

- Screen goes black.

- Keyboard becomes unresponsive [Numlock/capslock] don't toggle lights on the keyboard.

- The machine becomes unpingable and ssh into the machine no longer works.

----------------------------------------------------------------------

I am interested in helping resolve the problem but don't really know what information to provide.  Any guidance would be appreciated :)
>How-To-Repeat:
I haven't found a way to repeat the problem consistently, it just happens within a day or two.

It doesn't seem to occur with any particular application, it has happened with only X running and no users on the machine.  It has also happened with many applications open and me interacting with it.
