Public bug reported:
Ubuntu 11.04, i386. Notebook HP NC6000 with Pentium M @1700MHz
I observe that Broadcom Corporation NetXtreme Ethernet adapter is not
reliable under heavy load. When I copy data to my notebook it is OK (but
I am not sure, maybe I am just lucky...). When I try to upload data from
my notebook to the server in LAN, I observe that network hands after few
seconds. I have to unplug and plug network cable to fix the problem but
it is a fix for several seconds and communication hangs again in a
minute. I found it is better for me to use external USB network adapter
that is slower than fast on board NetXtreme adaptor that hangs...
Details about HW:
Kernel module for Broadcom NetXtreme is tg3.
