Sorry for the top post, please try following patch:
http://people.freebsd.org/~sephe/if_bce.c.diff
This is probably the cause; I noticed it when bce(4) was ported to DragonFly.

Hi,
As the NIC's are coming UP (as indicated by messages on the console) the
system is trying to mount NFS file systems. At this stage if the system
does not produce the "Too many free rx_bd" error the system will be stable.
We are using Jumbo Frames with an MTU of 8192. The switches are Dell
PowerConnect 5324's. The NFS server is a Dell PE1850 with EM cards.
The bug can be triggered by NFS data (there was arround 600Mb of data in
the directory that I ran "cat * > /dev/null" in). Also the bug can be
triggered by heavy rsync traffic. (Rsync over ssh where the box crashing
is the SSH client, also SSH has the HPN patches applied to it.)
The box that crashed 4 times did so in the following sequence:
1) First boot with debug driver crash very shortly after nfs mounts
start/complete (Corrupt dump). "Too many free rx_bd" message is present
on the console before the crash.
2) Second boot with the debug driver system does not crash after cat *
over NFS. Crashes a few minutes after starting a rsync from an
identical PE1950 the system crashed (Again producing a corrupt core
dump). "Too many free rx_bd" message is present on the console before
the crash.
3) Third boot NFS crash was not tested. Restarted rsync process and the
system crashed again. (Core ok this time but log buffer not present in
the dump, or was empty.) Back trace indicates the driver crashed the
system at the same place as the next crash on this system and the only
core I have from a PE2950. "Too many free rx_bd" message is present on
the console before the crash.
4) Fourth boot again did not test the NFS crash. Restarted the rsync
process causing the system to crash. ( Core and log buffer present in
core, buffer and back trace at the end of this email.) "Too many free
rx_bd" message is present on the console before the crash.
5) Fifth boot of the system. No "Too many free rx_bd" messages appear
on the console. The system rsync's ~290Gb of data and is still up.
At each reboot the system was just left to reboot itself the system was
not powered off at any point. I have a PE2950 that went through a
similar cycle of crashes only to boot into a stable configuration 3-4
reboots later. (I have the last core available from this system.)
The system crashing above is a PE1950 with 1 5110 1.6Ghz Dual Core Xeon,
2Gb RAM, PREC5/i (2 * 80 Gb SATA RAID 1), PERC5/e (MD1000 3 * 500Gb SATA
RAID 5). The source of the data being rsynced was an identical system.
I have attached the patch for the driver we are running (patch is
against RELENG_6_2).
