But i had some lock panics :( Unfortunately, i couldn't get a ddb trace. But i could reproduce the problem with iozone from pkgsrc today. It panics in mutex_vector_enter with the message 'Mutex error: mutex_vector_enter: locking against myself' Trying to debug it currently. regards
I analyzed the problem a bit more and it is very odd. Someone uses a spin mutex on a single-processor kernel, which will never work because spinning on a single processor doesn't make sense. And mutex_vector_enter checks the type of a mutex and if it's a spin mutex and we do not run in multiprocessor mode then it panics. regards
