FreeBSD 6.2-STABLE FreeBSD 6.2-STABLE #1: Sat Jan 27 09:31:21 UTC 2007 konrad@stacja:/usr/obj/usr/src/sys/BIURKO.DEBUG i386
>Description:
Kernel crashes after killing kdm or kdeinit (for example when logging out of kde or sutting down the system). This problem appears only when kdm was invoked from /etc/ttys. When kdm is invoked from command line, everything seems to be ok.
