Good idea except when the original modprobe could cause a lockup of the box.... I was hoping there was a clean way of preventing a module from loading at startup via modprobe but then later being able to modprobe the module. My solution is to add this to /etc/modprobe.conf alias wct4xxp off alias zaptel off And when I need them: /sbin/modprobe crc_ccitt /sbin/insmod /lib/modules/$(uname -r)/misc/zaptel.ko /sbin/insmod /lib/modules/$(uname -r)/misc/wct4xxp/wct4xxp.ko Not clean at all and more of a hack. There should be SOME way of delaying loading of modules at powerup time. -- W
