Hi,

I have a problem with the Broadcom BCM5704C (Dual Gigabit=
 Ethernet) which 
is used by one of our servers (newsfeeder with 5.1-RELEASE and=
 diablo). 
The interfaces go down frequently if they have traffic (diablo=
 started) 
and I see the following kernel messages:

kernel: bge0: watchdog timeout -- resetting
kernel: bge1: watchdog timeout -- resetting

After this, the interfaces are up again for about 10-15 minutes.

The server is a Fujitsu-Siemens Primergy RX300 with one Xeon=
 2,4Ghz and 
2GB RAM:
http://www.fujitsu-siemens.com/rl/products/primergy/rx300.html

What I've done so far and what didn't help:

- Compiled a kernel with and without SMP/APIC (also switched 
Hyperthreading and APIC on/off in bios)

- tried various mediaopts/mediatypes on the interfaces and/or the=
 switch 
(Cisco 2924-XL, no VLAN, IOS 12.05.(2XU)), both are running on=
 auto now 
(100 BASE/TX, full-duplex, no crc errors). 

- tried different drivers:
http://people.freebsd.org/~wpaul/Broadcom/5705/
=3D> worked, but the problem was still there (even with _very_ low=
 traffic)
http://people.freebsd.org/~wpaul/Broadcom/busdma/
=3D> didn't work, I was unable to compile the kernel.
=3D> the driver which is shipped with 5.1-R is now used again.

- tried a different mtu (1505) on bge0.

Any help on solving this issue would be nice.

Regards,

Dirk Janssen
