Hello, all,

I have a Beagle Bone Black rev C, running the latest machinekit 
distribution.
I have been logging in with ssh as I don't have a micro-HDMI adapter cable
yet.  Everything works fine for 18 minutes, then it powers down.  just 
before
powering down, I see this message :
$ [  426.564569] EXT4-fs (mmcblk1p2): mounted filesystem with ordered data 
mode. Opts: (null)

Then, about a minute later it says :
Broadcast message from root@beaglebone (Mon May 19 16:19:26 2014):

The system is going down for system halt NOW!

the shutdown looks pretty normal until the end, where I see :
[ 1152.630360] EXT4-fs (mmcblk0p2): re-mounted. Opts: (null)
Disabling swaps.

I have run e2fsck by plugging the SD card into a USB card reader on my 
desktop system,
it finds no errors.

Anybody know what is going on?  I'm pretty baffled.  This 18 minutes to 
power down
seems to be pretty repeatable.

Thanks,

Jon
