I have a machine that crashes instantly on boot up on Linus' post-3.9 tree. (8c55f1463c1fd318d5e785f02b80bcc32176d342)
By booting with boot_delay=100, I was able to take a photo and capture the top of the trace. (For some reason, larger boot delay parameters seem to make it take forever before printing even a single character, which made this a pain to debug).
The WARN_ON it prints right before locking up is this in clockevents_program_event
208 if (unlikely(expires.tv64 < 0)) { 209 WARN_ON_ONCE(1); 210 return -ETIME; 211 }
booting with maxcpus=1 avoids the problem.
I'm still trying to get a complete stack trace, though it's painful due to the above reason.
Dave
