It also looks like the device_printf() format string is missing a newline. Try adding a device_printf() to aggch_init() to print out both physaddr and ess->baseaddr so that we can figure out where the calculation ch->offset = physaddr - ess->baseaddr; is going wrong. The source file is /usr/src/sys/dev/sound/pci/maestro.c
