Again, that isn't diagnosing the problem as much as just saying that 5.0
through 6.2 were all bad releases???  I doubt that can be the case.  Why
would the driver support for this machine (working FLAWLESSLY on 4.10)
now have bad drivers (this machine has been running 4.x for 4 years).

Fresh install ALWAYS (no migrate, I never go that route).

bge0: Broadcom BCM5704 A2, ASIC rev. 0x2002
bge1: Broadcom BCM5704 A2, ASIC rev. 0x2002

-bash-2.05b$ dmesg
pid 31611 (milter-greylist), uid 25: exited on signal 3
pid 43464 (httpd), uid 80: exited on signal 6
pid 86995 (imapd), uid 2151: exited on signal 6
pid 85706 (httpd), uid 80: exited on signal 6

pid 45621 (httpd), uid 80: exited on signal 6
pid 45617 (httpd), uid 80: exited on signal 6

The greylist entry is a standard 3am cron restart.
