sysctl -a on FreeBSD 5.1 CURRENT == reboot

[Axel S. Gruner]

Hi.

Yesterday, 03.07.03 i did a cvsup and make world on my machine to
FreeBSD 5.1-CURRENT.
The strange thing is, when i type "sysctl -a" now, the system will
freeze. After a few second, it will automatically reboot. No logs for
that.
Is this a know problem?
