Yesterday I ran Tobotras' crashme-2.1 for 10 hours with:
nice -20 ./crashme +2000 1234 100 10:00:00 2
I only now noticed the following oops in dmesg (the system is
still up and running!):

I won't be able to answer any questions as I'm going to have a

baby girl, guess what day? Sept 17 (==Linux)! Virtual cigars
and cognac to everybody!).
