Description Jeff Needle 2002-08-14 16:24:49 UTC 
On a system running Milan Beta4's uniprocessor kernel, the machine locks
bringing up the interface for an e1000 card adapter only when the cable is
plugged in.  
Adapters tested: copper gigabit (82544E1 chipset) and fiber gigabit (82543GC). 

Bug does not exist on RHL 7.3 or Milan beta 3.  Tested with different adapters,
slots, and systems.

Procedure for locking the machine after logging in:
# these first 3 commands are optional, but make it clear that no other network
devices are interfering

echo 0 > /proc/sys/kernel/hotplug    # turn off hotplug so loading e1000.o will
not cause eepro100.o to be loaded
rmmod eepro100                       # go ahead and get the e100 devices out of
the picture
modprobe e1000                       # load driver

# be sure the network cable is unplugged.  now a test run, just for kicks:
ifconfig eth0 x.x.x.x netmask x.x.x.x             # does _not_ cause a hang
ifconfig eth0 down

# now plug in the network cable
ifconfig eth0 x.x.x.x netmask x.x.x.x

#machine is now hard locked
