Found a neat one. If you tip to a printer on a parallel port, and you do a Control-T a couple of times and return, the solaris 2.4 machine panics on bad rmfree. It seems to be somewhere in the driver code that a timeout leads to the panic. I have an open call to Sun right now. I have the latest lp and kernel patches installed. Should know more on Monday..
