During the compilation of the ACPI module (if I remember well) the compilations stopped because was used a gcc flag not supported during the kernel compilation that I keep only in CFLAGS (-mfpmath=sse) . The rest of the kernel has been compiled with COPTFLAGS, but that specific driver has been compiled with CFLAGS. Bye Marcellohelp
