Makes sense - that just happened to be what the kernel requested at the time. > The driver is trying to reset the card, however it is failing the reset. > > "AEN drain failed, retrying." means your card is not responding. I assume it's trying to flush all pending commands or somesuch?

Too bad, it was a good card :-( (It's bought off of eBay, so I don't think there's any hope for a replacement). Thank you very much for the help! Wait - how is it that a driver can't reset the card, but a hw reset always can? Is there some more fundamental type of reset possible, than what the driver currently tries? Or would that require resetting everything? It would be ultra-neat if the driver could just stall for a few seconds (or even a minute). That'd be so much more bearable, compared to a terabyte-class raid5 just suddenly failing. Or at least, maybe the driver could try to reset the card a few more times? Sometimes it seems to work after a couple of attempts. -- Regards, Christian Iversen
