Hello there, I have a problem to ask.

Broadcom wired Ethernet card stop working on high network load
such as coping within LAN network

My laptop run with ubuntu 9.04 (32 bit)
kernel 2.6.28-13-generic

lspci -v result is:

08:09.0 Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX (rev 02)
Subsystem: Fujitsu Limited. Device 123b
Flags: bus master, fast devsel, latency 64, IRQ 20
Memory at d4214000 (32-bit, non-prefetchable) [size=8K]
Capabilities: [40] Power Management version 2
Kernel driver in use: b44
Kernel modules: b44


dmesg |grep b44 result is:

[ 4.854253] b44 0000:08:09.0: PCI INT A -> GSI 20 (level, low) -> IRQ 20
[ 4.928164] b44.c:v2.0

Is there any work around for this problem?

Thanks
