it was one of the testcases, but i haven't figured out which one yet. it
doesn't do this for every testcase...

probably, it crashed my machine 3 times before i figured it out :-)
if you do "echo 0 >> /proc/sys/kernel/unaligned-trap" before you run the
test then it should SIGBUS when it does this...
i'll try to debug this a bit more as well. but we shouldn't crash the
kernel in any case :)
