Description of problem:
I loaded Serven on my workstation at work. After booting up I found though there
were no errors and the ip information was set correctly my network didn't work.
I tried didn't cables, a crossover cable to another computer, e100 and eepro100
drivers. Finally I added acpi=off apci=off to the kernel during boot. Suddenly
the network was working again. Next I tried just apci=off, and it didn't work
again. Then I tried acpi=off by itself and it worked.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Load Serven
2. Install a Intel 10/100 card
3. Configure network with netconfig or neat
4. modprobe e100 or modprobe eepro100
5. service network start
Actual Results: Everything looks good, but networking doesn't work
Expected Results: Everything looks good, and networking works
Can you post the output of 'dmidecode' for your system?
That's /usr/sbin/dmidecode -- run as root.
Please also post the output of /usr/sbin/acpidmp

I also tried acpi=nopci while I was at it and it didn't help.

I don't have Gigabyte/AMD/Award or Abit/AMD/Phoenix systems handy,
but severn on my Intel/Intel/AMI boxes seem to talk to e100 just fine.
Is it possible to get the dmesg, /proc/interrupts, and ifconfig output
for both the success and failure cases?

ACPI VT86/Award PCI interrupt patch.
This patch has fixed the ACPI interrupt problem for similar systems.
Please try applying it to a copy of your Severn BETA1 kernel to
see if works for you too:

Dave, please take a look at this patch, thanks.
AFAICT, we have an improved variant of this patch already merged since test2
Personally, I'm convinced this is fixed. I can't repeat any problems with or
without acpi=on using e100 or e1000 on several boxes.
