OK, I've seen your error once now.  I guess I just need to run the test a number of times looking for it.  I am investigating.

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.

I'm still seeing the SEGV with my latest patches on V3.12 on a Panda.
