If you build a kernel with the ACPI_DEBUG option, this option gets passed to the module build in opt_acpi.h, but the kernel panics on boot because the symbol AcpiDmDumpMethodInfo is undefined in the module. The problem is that the Makefile for the acpi module needs to know whether ACPI_DEBUG is defined because it wants to append some more files to SRCS in this case. One of the extra source files contains the definition of the undefined symbol. .if ACPI_DEBUG CFLAGS+=-DACPI_DEBUG SRCS+= ${DBSRC} opt_ddb.h: Makefile echo "#define DDB 1" > ${.TARGET} .else opt_ddb.h: Makefile echo -n > ${.TARGET} .endif
