FreeBSD 5.4-PRERELEASE as cvsupdated today won't build, OS crashes

[O. Hartmann]

I did a cvsupdate several minutes before and tried to build world.
A buildworld stops as shown below in building libkvm.

Also, the system is really instable after I build the kernel for
itself. Under heavy load, the machine get stuck and freezes.

I have no more informations due to remote control of the system.
