X11 server crashes -- a partial fix

[kl522]

Hmmm - I get it, but I was hoping for something like a kernel parameter to change. Maybe someone else has a suggestion?

My guess is this is probably related to X11 display driver. Maybe you can check if all the "problematic" machines are using the same X11 display drivers. Or you could try using different display drivers to see if they make any difference to this behaviour.
