I can't find that string anywhere in the sources. Are you sure "rm.mutex_mtx" is correct? >KDB: enter: panic >[thread 0] >Stopped at kdb_enter+0x30: leave >db> ps axl >Symbol not found Should be just "ps". There's no point in this case because the system panic'd before it finished booting. Instead, run "trace" and post the results. I suggest you read ddb(4) and the developer's handbook URL that I posted. >db> show witness >(too much info for me to type (haven't got the serial console running >yet, I can however not find any mention of an rm mutex) One option in this case is to take a photo and put it up on the web somewhere. -- Peter Jeremy
