Anyone else with b44 network issues?

[Mary Ellen Foster]

Is anyone else experiencing symptoms like the following:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=154512

Summary: if I plug into the network at work, as soon as I try to
download anything, the network card goes into an endless loop of:
Apr 14 09:59:44 localhost kernel: b44: eth0: Link is down.
Apr 14 09:59:47 localhost kernel: b44: eth0: Link is up at 100 Mbps,
full duplex.
Apr 14 09:59:47 localhost kernel: b44: eth0: Flow control is off for
TX and off for RX.
Apr 14 09:59:52 localhost kernel: b44: eth0: Link is down.
[... lather, rinse, repeat until I stop the attempted download]
I can't do anything at all on the network because it's far too slow
with all these restarts.

However, if I use my broadband router at home, these symptoms don't
occur. With the original Test 1 kernel (which I can't find anywhere!),
I'm pretty sure I was able to make it go away by either booting the
non-SMP kernel or disabling acpi on the boot line; but with Test 2,
nothing I try has been able to make it go away.

Is anyone else seeing this? This is on a Dell Inspiron 5160 laptop,
and the network card identifies itself in lspci as:
02:01.0 Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX (rev 02)

Thanks for any suggestions you can give,

MEF
