AMD and other Intel processors will also have the same problem (AMD seems to have lifted the logic circuit designs directly). The problem has definitely been around since the P3 days (the P3 is where I saw it first). The only thing that's going to be a factor is amount of memory in the system, and certain tuning parameters, in which case the workaround is accidental. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
