Hi Ted, kernel hackers,
Some time ago, I noticed the fact that for every newly
executed process, the function create_elf_tables requests 16 bytes of
randomness from get_random_bytes. This is easily visible when calling
while [ 1 ]

Hey folks,
looks like we still have some oops in i915. i915 maintainers do you have
any ideas what's going on? I will try to trigger that oops later today
and provide more information.
