[1.] One line summary of the problem:

e100 fails under heavy load after ACPI suspend

[2.] Full description of the problem/report:

After an ACPI suspend to memory (echo -n mem >/sys/power/state), my e100
card stops working under heavy load.  wget of a large file on a local
server hangs after a few seconds.  Occasionally, 
NETDEV WATCHDOG: eth0: transmit timed out
appears in dmesg.  'rmmod e100; modprobe e100; dhclient eth0' solves the
problem, but only until the next heavy usage.

If I should be submitting this to the ACPI people instead of to you,
please let me know and I will do so.

[3.] Keywords (i.e., modules, networking, kernel):

e100, acpi

[4.] Kernel version (from /proc/version):

Linux version 2.6.4 (scjody@debian) (gcc version 3.3.3 (Debian)) #1 Thu Mar 18 20:18:50 EST 2004
Applied acpi-20040311-2.6.4.diff.bz2

[5.] Output of Oops.. message (if applicable) with symbolic information
     resolved (see Documentation/oops-tracing.txt)

n/a

[6.] A small shell script or example program which triggers the
     problem (if possible)

wget-ing a large file from a local server is sufficient.
apt-get install xxxxx will also do it most of the time.
