List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 09 Apr 2014 05:42:32 -0000 I am using snapshot build (the latest BeagleBone snapshot build: FreeBSD-11.0-CURRENT-arm-armv6-BEAGLEBONE-20140323-r263665.img Everytime I do reboot or poweroff, I get the captioned error. I googled it, I think I am not alone. Also, I have the same problem with portsnap fetch. Any idea how to fix it? Thanks.
