I was actually considering debian over freebsd on a dual AMD64, but if there are no settings that will make it stable... Nevertheless I'd be willing to help debugging ZFS on that machine (Dell T105) as soon as I receive it in a couple of weeks, as I'm in no rush to getting it into production (just tell me what to do ;) ). > > ----- Mensaje original ---- > De: Spike Ilacqua > Para: Ender > CC: freebsd-fs@freebsd.org; freebsd-stable@freebsd.org; Johan Ström > Enviado: martes, 8 de abril, 2008 18:13:32 > Asunto: Re: ZFS deadlock > >> Depending on your work load you are just buying more time, so >> "reasonable" is a matter of perspective. :( I didn't see if you said >> you are on 32bit or 64bit?
