Comment 1:

What type of arm system are you installing on. The atomic uint64 tests fail on arm5
because there is no way to do that on these systems. 
It wasn't clear from the original error report if you were passing GOARM=5

GOARM is set to 5.

Comment 3:

The math/rand test failure is not fatal, you can verify that by 'go test -short
math/rand' manually.
The sync/atomic test failure is a real issue, but it's a dup of issue #3331.
Thanks for reporting.

Status changed to Duplicate.

Merged into issue #3331.
