Follow the simple rule in the atomic package: "On both ARM and x86-32, it is the caller's responsibility to arrange for 64-bit alignment of 64-bit words accessed atomically. The first word in a global variable or in an allocated struct or slice can be relied upon to be 64-bit aligned." Tested on a system with /proc/cpuinfo reporting: processor : 0 model name : ARMv7 Processor rev 1 (v7l) Features : swp half thumb fastmult vfp edsp thumbee neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x0 CPU part : 0xc0d CPU revision : 1
Test fails without this fix on armv7l:
go test: -race is only supported on linux/amd64, freebsd/amd64, darwin/amd64 and windows/amd64

Two small fixes to make tests and etcd itself working on an armv7l machine.
