Since the last update and make world on Friday, 12th March I get a

Fatal trap 12: page fault while in kernel mode [...] current process:

(swi2: cambio)
Can you show the stack traceback from the kernel core?
We had a problem a while ago at Isilon that I can't tell if it's
related. In our case, the camisr() routine was called after panic(9)
started and before the halt of other processors. This did Bad
Things(TM) since the mtx_lock is a no-op after panicstr is set.
We solved it locally by wrapping camisr() in a local cambio_swi()
routine that only called camisr(NULL) when panicstr == NULL.

Hello.
I will do as soon as possible. The box is in production at the moment
and I've less time to put everything into debugging to provide more
details.
Just in case: does the kernel automatically save the screen with the
dump information? If not, I have no other terminal facility to get a
dump via the classical way.

Since yesterday, this problem went away! This is mystical. After deactivating
radeon.ko and the virtual box stuff I tried again with a new build of world
and - voila! - everything worked again. This is strange ...

If possible set a dump device and use the following in your rc.conf:
crashinfo_enable="YES"
dumpdev="ADD-DEVICE-HERE"
After the crash happens look for core.txt.N files in /var/crash.
You will probably want to look over the crash info and scrub it of
vital information to comply with your companies policies. It is very
verbose.
DDB as I have heard can be configured AFAIR to textdump but I have no
knowledge of that.
Good Luck,
