That is correct, the imprecise external abort error most of the times
lead to a kernel panic but sometimes it doesn't and the the system finish

I've pinged Kukjin again yesterday to pick the fix and he said that will
do it this weekend [0]. So hopefully exynos5420 machines will boot again
in linux-next soon after being broken for weeks.
