I have no idea how big the soundblaster microcode being loaded actually is, that is if the reduced size of 0x1f00 will be sufficient. Aside of that I don't see a problem - I don't see how the old ioctl can possibly have been used before so there isn't a compatibility problem. Or you could entirely sidestep the problem and use request_firmware() but I guess that's more effort than you want to invest. > This is an old ISA driver, so the impact must be very low. True. I notice that sort of stuff in automated mass builds - not necessarily the sort of kernels one would actually use. Still build errors are annoying :) Ralf
