After I recompiled the kernel, everything I do not know much 'bout FBSD kernel, but AFAIK page fault trap is generated, if the opreating system could not swap in a page which is required by the processor. If you say, after a recompile of the kernel all went ok, it could be much helpful to the developers, if you resent this question plus an output of the original and new dmesg-output (if different) to mailto:stable@freebsd.org Jens > works fine.
