But I have now the possiblity to avoid the hang-ups of my machine by unloading the 1394-modules before generating a bus reset und insmoding them afterwards -> so it is definitely a bug in the driver. Concerning the other thing I mentioned, the several bus resets on bootup, I have not checked this yet. So I cannot tell you if it depends on whether the driver is in the kernel or in a module. Maybe I check this on Tuesday or Thursday (if I have time). 3) If it is not recommended to put the driver into the kernel, but rather to put it into a module, this should be mentioned in the documentation (/usr/src/linux/Documentation/Configure.help). If one does not intend to update the driver more frequently than the driver, it makes much sense to put it into the kernel, because then you do not have to bother around with the insmod's. So if it is depreciated to compile it into the kernel, there should be an explicit warning.
