I've not seen this to be the case, and I still run i386 in several = virtual machines as well as on my firewall. Running in a virtual = environment isn't good support for dropping i386, frankly.

Are there specific = bugs in i386 that haven't gone fixed for a long time? Basically, I see no benefit to this move. At least none has been = articulated. Warner=
