>Description:
if psm is enabled and, for instance the mouse is not connected or ifthere is no ps/2 connector, the kernel panics during probe.
>How-To-Repeat:
enable psm driver and unplug your ps/2 mouse, system panic while booting
>Fix:
in file /usr/src/sys/i386/isa/psm.c, delete each line"free(sc, M_DEVBUF);" before "endprobe(*)" and modify "endprobe" macroby inserting "free(sc, M_DEVBUF);" just before "return (v)"
