Kernel crash FreeBSD 10 on BeagleBone Black

[Lundberg, Johannes]

A bit embrassing but maybe this was not something fatal.. I make a new
distribution which has ports already installed to test compiling smaller
programs and when I started compiling a program I got the a similar KDB
message but the system kept running as normal.

Perhaps if I had waited a bit longer for the portsnap snapshot extraction I
could have seen that the system kept on running. However, I have not tested
this yet.
