ok - i've tried it and it works fine - no more crashes :-)

ok - now i've been upgrading the 950412 snap machine to 2.0.5 release and now
only freebsd is there on the disk (before it was half linux half freebsd) -
now i've enough space to create crashdumps - and i get them (about the problem
with the other machine i'm not able to produce crashdumps with i'll report
more detailed later here) - thus you'll get more info about this nfs-xdm
problem within the next days (happy kernel debugging :-)
