A PentiumPro user is occasionally getting the trap type 29 when using the psm driver (PR i386/3462). What does this trap mean? The trapped instruction doesn't look remotely like an invalid instruction. sys/i386/i386/trap.c doesn't supply a message for this trap type. He is using PentiumPro 200Mhz on ASUS P/I-P65UP5. > Using a PS/2 mouse with std.
