Dumping then restarting

Yesterday I installed FreeBSD on my laptop today when I turned on my computer it said dumping 10%..15%..etc
Then it says dumping successful then the computer restarts. What's wrong?
It worked yesterday
What FreeBSD version did you install, and on what hardware? Also; are you sure there's nothing wrong with said hardware?
"Latest" doesn't tell me much because there are several releases; there's 10.4, 11.1 and the developer snapshots.
You first have to find out why it is dumping its core. Most of the time this happens because of some hardware defect. Especially if the machine was running fine before. But without knowing any of the details of the crash it's going to be difficult for us to tell you why it crashed and what needs to be done to fix it.
