From: Rami Rosen To: Kevin Cruz Cc: Johannes Berg , Intel Wireless , "linux-kernel@vger.kernel.org" , "linux-wireless@vger.kernel.org" Content-Type: text/plain; charset=UTF-8 Sender: linux-wireless-owner@vger.kernel.org List-ID: Hi, Could it be that debugfs is not mounted on your filesystem ? In case mount | grep debugfs returns nothing, you can run: mount -t debugfs none_debugs /sys/kernel/debug and try again. Also make sure that CONFIG_MAC80211_DEBUGFS is set location is: -> Networking support (NET [=y]) │ -> Wireless (WIRELESS [=y]) Regards, Rami Rosen On Tue, Oct 2, 2012 at 1:06 AM, Kevin Cruz wrote: > Hey Johannes, > None of this should be too much of an effort for me.
