Hi David,
I finally got the uprobe-v2 branch of https://git.linaro.org/gitweb?p=people/davelong/linux.git;a=summary working on my samsung arm chromebook (needed to use a newer exynos5250-snow.dtb file). I reran the at_var test with the newer kernel and do not see the sigsegv.
I am going to rerun the test tests with this kernel and see if the problem went away with the newer version of the patches.
