(forgot debian-arm cc) Hi Mike, As author of that page/script, that config setting isn't actually required, it's more useful for debugging purposes while compiling the kernel... I just haven't configured it to be a selected option yet, so it's just always on by default in my script... (and i dropped using ubuntu around 11.04, so i appreciate the error report and will make it selectable..) http://cateee.net/lkddb/web-lkddb/DEBUG_SECTION_MISMATCH.html It's now fixed, so other ubuntu 11.10 user's should run into the issue: https://github.com/RobertCNelson/imx-devel/commit/0687fc2e681b3a960c62e996f2bd9d42aa8ce640 Regards, -- Robert Nelson http://www.rcn-ee.com/ -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
