But as Stelian also reported problems on his fresh ARM port with the in-kernel test, I cannot exclude that there /might/ be a problem in the benchmark. As I don't have any ppc64 hanging around somewhere, we will have to go through this together. Things I would like to know: o When and how does it crash? At start-up immediately? Or after a while? o Are there any details / backtraces available with the crash? o Does -t2 work? o What happens if your disable "rtdm_event_pulse(&ctx->result_event);" in eval_outer_loop (thus no signalling of intermediate results during the test)? Does it still crash, maybe later during cleanup now?
