Hello, I just downloaded 2.4.0-ac1 , and received the following error during 'make dep': make -C acpi fastdep make[4]: Entering directory `/usr/src/linux/drivers/acpi' /usr/src/linux/Rules.make:224: *** Recursive variable `CFLAGS' references itself (eventually). Stop. I saw Keith's email about moving to make v3.77 or v3.79, if you are using v3.78 . I confirmed that I am using make version v3.77 . So, it appears that v3.77 doesn't work to compile drivers/acpi . Should we look into patching Changes to make 3.79 the minimum version for make, or 'fix' drivers/acpi (Makefile, Rules.make, etc.)? Has v3.79 been confirmed to work? I understand v3.78 is confirmed broken.
