From: Scott Long [mailto:scottl@freebsd.org] ... system locking up > Please try the latest aac driver sources. Your commit comment is "Collapse aac_map_command() into aac_startio(). Check the AAC_QUEUE_FRZN in every iteration of aac_startio(). This ensures that a command that is deferred for lack of resources doesn't immediately get retried in the aac_startio() loop. This avoids an almost certain livelock." This livelock, would i not still be able to drop into ddb via the console? i'm trying it out now, will post back with results. The lockup varies between every couple of hours and ~3 days, so it will take a bit. --don
