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.
Below is the log from BeagleBone Black UART:
