>Description:

Hi,

When I try and boot the standard kernel with ex0 (Intel Etherexpress
Pro 10) enabled, the kernel panics during network initialisation.

This is a secondhand AMD 486 DX2-66 I bought a week ago to be a firewall for
my adsl connection. I initially tried 2.7 and it crashed (same place), so i
downloaded the latest 2.9 snapshot (26/04/2001), and did an ftp install
from my pc, from floppy29B.fs (which worked fine) but when I try and
boot from the standard kernel it panics right after:
starting network

The computer is an AMD 486 DX2-66, 16Mb ram, and 2 x Intel Etherexpress
Pro 10 ISA cards, and a 420Mb HD.

If I disable ex0 at boot time then everything works fine (except the
network of course ;)  -- the dmesg at the end was saved to floppy by
doing this.

The first network card is set to: (standard kernel config)
UKC> find ex
138 ex0 at isa0 port 0x320 size 0 iomem -1 iosize 0 irq 5 drq -1 drq2 -1
flags 0x0

The second is set to port 0x300, irq 3, but this device wasn't even
added to the kernel yet.  ISA Pnp is disabled on both cards.


Here is the panic message:

if it would be usefull i can type in the rest of the numbers

here is the output of dmesg if i boot with ex0 disabled:

I've tried just using one card (both of them individually) with a bunch of
different port / irq / isa slot / card combinations and none of them
work..

if there is any more information i can provide you with, or things
I can try, then please let me know and I'll do what I can ASAP.

Thanks Heaps for all your hardwork and producing an excellent product
and sorry about throwing such crappy hardware at it.

Thanks again,
Tom

>How-To-Repeat:

boot the generic 2.9 kernel (or 2.7 kernel) with ex0 enabled.

>Fix:

boot -c and disable ex0
