FYI, I'm seeing the same periodic aborts. For example, here's my boot
of next-20140910:
http://images.armcloud.us/kernel-ci/next/next-20140910/arm-exynos_defconfig/boot-exynos5420-arndale-octa.html
However, my userspace is much simpler and doesn't seem to cause a panic,
so my boot tests report passing. (I should fixup my scripts so these
imprecise aborts are reported as a FAIL.)
I'm glad you pointed out that it happens only with exynos_defconfig and
not multi_v7_defconfig because I noticed that too. I haven't had the
time to track it any further than that, so maybe the exynos folks can
help track it down from here.
Thanks for reporting this,
Kevin
