ACPI S3 fails to re-init NIC on Asus A7V

[Carsten Aulbert <carsten@welcomes-you.com>]

Hi all,

Please consider the following problem:

Home Server (daisy):

Asus A7V board
Duron 650 MHz
Debian sarge (not 100% up2date right now - from March 22nd)
SiS900 (also tried 3Com 3c509-TX-M without a change)

Kernels tried:
2.4.22 (IIRC), 2.6.4, 2.6.4 with acpi-patch 20040311, 2.6.6

Suspending to S3 works fine, resume also (except with the 
onboard-Promise chip, but that's not a big issue), however, trying to 
use the network after resume gives
NETDEV WATCHDOG: eth0: transmit timed out

This also did not help:
/etc/init.d/networking stop
modprobe -r sis900
echo 3 > /proc/acpi/sleep

[resume]

modprobe sis900
-> module is loaded successfully
/etc/init.d/networking start
-> sets the static routes correctly
pinging a machine on the network yields the same error as before.

(Also tried 3Com 3c509-TXM to no avail)

To spare you about ~1000 lines of output, I've put the output of dmesg, 
lspci -v, acpidmp and an excerpt from /var/log/syslog with enabled 
sis900-debugging here

Does this problem ring any bell, do you need more input from my side? 
I'm currently running out of options and ideas.

TIA for any help

Carsten
