I don't know whether there are any serious problems involved with this, but one thing that is definitely annoying, is that the process list fills very quickly when modules are loaded/unloaded on demand, because 2 new processes will be created every time the driver for a scsi adapter gets loaded. (I guess, this happens with all scsi host modules - in my case, the "culprit" is a qlogic fibre channel driver that gets loaded only when needed.) Regards, Peter Daum
