I also have a chromebook running 3.4 and it is trivially easy to crash it 
with some simple perf_event tests I have (not the fuzzer, but just the 
regular validation tests that test counter overflow).

Like Dave, I didn't bother reporting the problem because I figured 3.4 was 
too old for anyone to care about and it was a struggle getting any 
distro/kernel installed at all on the system let alone trying to boot 
something close to current mainline on it.
