I never get lockups, but I am running an old Neptune-based dual P90 (it was quite something at the time I bought it to do FreeBSD SMP hacking using Jack Vogel's original SMP work from October of 1995). > I haven't done a lot with X on this system, but everything > I've done has worked fine.

As an experiment, really, really I/O load your system (I think that serial I/O might be the modet I/O bus intensive), and then bounce back and forth between the console in X and a text console, and see if things lock up.
