quick answer: disable ACPI on boot choosing option 2!
Later follow http://doc.pfsense.org/index.php/Booting_Options#Disabling_ACPI to make it permanent.
long history:
I was having another problems with that machine… and it was not production yet... so I started to debug.
I was worried about how slow it was!
I was worried about error messages about timeout and missing interrupts on NICs.
I was worried about PPPoE do not work JUST FOR ME ... and I REALLLY WANNA TO HAVE PPPoE to avoid double NAT!
So I started to change settings / replace items!
I replate 2 NICs twice
I replace all CABLES involved
I replace ADSL modem
nothing helps.
I choose DHCP to WAN and discovered my future pfSense2 firewall was taking 1 minute to get an IP from modem... on a direct connection.
So... should be something on machine...not in pfS2, not in other HW (NIC, cable, modem).
With that information was easy... my first tought was to disable ACPI... a long history of problems with it (never one had included this sintoms!)
in just one minute I was a HAPPY user!
Now I'll SCREAM this in ANY forum I can find SOMEONE with PPPoE problem... it's a simple and quick test!!!
