Please enable as much kernel debugging options as possible and rerun the
test - our mind readers are currently on vacations, so we fail to
find a problem.

If there will not be any signs of the problem, try to add several printk
into main geode crypto functions (there are not that many of them) or
press various sysrq combinations to determine where stall happens.
