Description Jianqin Qu 2003-05-10 13:01:54 UTC 
More tests showed that this problem does not appear every time at boot 
on my Dell Optiplex 160L.
 
I found a tempory workaround for that.  When the problem occurs, simply 
shut down your computer completely (not just switch off the power button 
on your computer, but also detach your power cable!!! )   and  wait for 
sufficiently long time  and  then restart your computer to boot into 
FreeBSD 5.2.1 directly.   Here sufficiently long time varies, but 30 
minutes seems sufficient for my case most of time.

If  you switch off your computer power button without unplugging the 
power cable and the LED light on the system board is on, then after some 
time (several hours) when you boot your computer into FreeBSD 5.2.1, 
this problem almost certainly occur.

Rebooting into FreeBSD 5.2.1 release from another operating system 
installed on the same box  may reproduce the problem too.  Particularly 
rebooting into FreeBSD from a Linux system with a NIC driver of version 
3.0.7 from BroadCom  always results in the occurence of this problem. 
When the problem occurs, the link and activity indicator of the NIC are 
both off.   So it seems the bfe driver fails to reset the NIC card to a 
correct state in some cases.

A patch with the bfe driver  is attached, which fixes the bug.  The 
patch is against 5.2.1 Release and had been tested with it.   The 
patched file "if_bfe.c" is also attached for reference.

Below is the ouput from "dmesg", whose bottom lines state the bug in bfe drivers in a very clear way by itself.

Bug-fix with "bfe" driver
How-To-Repeat: Install FreeBSD 5.2.1 (i386) to any machine with a Broadcom 4401 Ethernet card  and the problem arises when you boot FreeBSD

Sorry, the wrong files were ataached to last message. The correct
files for patches are attached to this message.

Comment 4 Jianqin Qu 2004-05-15 02:56:55 UTC 
Sorry, the patch attached with previous message are either wrong
or somehow gargbled. So now I'm putting it on the URL:

     http://www.jexplore.com/~jqu/bfe_current.patch

The patch is made against FreeBSD-current, but it's tested to work
for FreeBSD-5.2.1-Release too. It should work for 5.2 as well.
Please check out and have a try. Just type:
    # cd /usr/src
    # patch < /path/bfe_current.patch
