NIC driver or what?

[namtab]

I'm on latest on HEAD: 2.1-BETA1 (i386) built on Sun May 5 07:29:51 EDT 2013

This is my setup:

–------------Internet---------------
                        ^
                        |
      ------------------------
      |                                |
  ADSL modem              3g Modem
      |                                |
      |                                |
  NIC 1(fxp2) WAN          NIC 2(fxp3) OPT1
      |                                |
      ----------pfsense--------
                        |
                    NIC 3(bge0) LAN

I only enable fxp3 when ADSL goes down (3g is a time based contract, so cannot do failover).

The problem:
Every morning I find NIC 1 down, with interface status bouncing between "up" and "no carrier".
Log entries:

May 6 11:56:37	check_reload_status: Linkup starting fxp2
May 6 11:56:35	kernel: fxp2: link state changed to DOWN
May 6 11:56:35	check_reload_status: Linkup starting fxp2
May 6 11:56:35	php: : HOTPLUG: Configuring interface wan
May 6 11:56:35	php: : DEVD Ethernet attached event for wan
May 6 11:56:33	php: : DEVD Ethernet detached event for wan
May 6 11:56:32	kernel: fxp2: link state changed to UP

This loops continuously, with CPU on 100% with check_reload_status, until eventually internet access goes down completely, with no particular log entry.
I started having this problem with the snapshots from april…
I tried everything: changing cable, changing NICs with brand new ones, even changed hard drive as SMART status was not looking too good.

Today ADSL went down, so I enabled OPT1 (fxp3). Started having the same identical problem with that interface:

May 6 11:56:37	check_reload_status: Linkup starting fxp3
May 6 11:56:35	kernel: fxp3: link state changed to DOWN
May 6 11:56:35	check_reload_status: Linkup starting fxp3
May 6 11:56:35	php: : HOTPLUG: Configuring interface opt2
May 6 11:56:35	php: : DEVD Ethernet attached event for opt2
May 6 11:56:33	php: : DEVD Ethernet detached event for opt2
May 6 11:56:32	kernel: fxp3: link state changed to UP

Everything functions ok after a restart, so I setup a cron job to "shutdown -r now" every early morning, but this is clearly a hack, and restarting during work hours is a no-no.

Have the drivers been recently modified? What am I missing?

I'm really desperate, please give me hand on finding this bugger…

I˙m willing to cooperate fully to resolve this issue or bug if it trully exists...
