I had a similar thing happen with make installworld. I went into single user mode, did make installworld, and then left the computer for a few hours until it was done (this was a month or two ago when make installworld took a long time). When I came back, the machine had rebooted very much like the error below. However, make installworld had finished. This happened to me twice. I never bothered with it, as it did not adversely affect me. I was not connected to the internet in any way (is the computer connected in single user mode anyway?) as I use a dial up connection, and it was not on. Well, now I have DDB switched on. Next time it happens I'll get more details. Benjamin Gavin wrote: > > Hi all, > Just thought I would add a little something to this discussion about > rebooting.
