Hi, We've used Systemtap on a Debian derivative with ARMv7 + hard-fp ABI and it works fine as long as kernel Kprobes works fine. There were some fairly serious Kprobes ARM/v7 instruction emulation issues fixed in upstream Linux kernel in spring, after which Systemtap started working fine on ARM.
These kind of issues may show up on test-suite run e.g. as reboots.
