Hi, I'm trying to troubleshoot not being able to set the Regulator Domain on a custom Yocto 3.14 kernel with a Marvell 88W8887/at91_mci driver on ARM. Running 'udevadm monitor --environment kernel' there are no kernel udev events being triggered. I've checked the following common items, crda is installed in '/usr/sbin' (version 3.18), wireless-regdb is installed at '/usr/lib/crda/regulatory.bin', '/etc/modeprobe.d/cfg80211.conf' has 'options cfg80211 ieee80211_regdom=US' & I have udev rules pointing to '/usr/sbin/crda' in both '/etc/udev/rules.d/' & '/lib/udev/rules.d/'. I have 'COUNTRY=US' set and when I run crda I get 'Failed to set regulatory domain: -7' and with no kernel udev events in the background and no cfg80211 messages in dmesg. Oddly if I use wpa_supplicant to connect to an AP and then stop the wpa_sup service then cfg80211 shows up and kenel udev messages fire and I'm able to set the reg domain via 'iw reg set'. Any idea's on what may be going on here or what I could check would be most appreciated. Thanks, Matt
