Re: kernel: spurious 8259A interrupt: IRQ7

i have a similar problem with a sharp actius um32w with a RealTek 
RTL8139 and an Intersil Corporation|Prism 2.5 Wavelan chipset' wireless 
card (see my message on 8-may to fedora-test-list for details).  using 
stock kernels the wireless card is configured as eth0 and the ethernet 
card as eth1.  then it configures them both again and confuses eth0 and 
eth1.  kudzu then tries to configure the wireless card as eth2, 
redhat-network-config is totally confused.  the ethernet card is working 
 fine, the wireless card is not functioning at all.  problems started 
with 2.6.5 kernels as best i can recall but i wiped out all the kernels 
before 2.6.5-1.327 to make space so i can't be totally sure.

Hello,
I have a toshiba laptop with a miniPCI EL-2511MP PLUS 802.11/b card in it.
I am running kernel 2.6.5-1.358 with all of the updates as of today.

I am a bit confused (understatement)

I just lost ethernet connectivity and had to power cycle the laptop.  I
was getting so many messages written to /var/log/messages that the system
was unresponsive.  I was using XMMS listening to radio station.

Messages start with:

What I am really confused about are the following output from dmesg.

eth0: Station identity 001f:0009:0001:0004
eth0: Looks like an Intersil firmware version 1.4.9
eth0: Ad-hoc demo mode supported
eth0: IEEE standard IBSS ad-hoc mode supported
eth0: WEP supported, 104-bit key
eth0: MAC address 00:02:6F:04:64:6A
eth0: Station name "Prism  I"
eth0: ready
8139too Fast Ethernet driver 0.9.27
divert: allocating divert_blk for eth1
eth1: RealTek RTL8139 at 0x3000, 00:02:3f:8f:19:0e, IRQ 10
eth1:  Identified 8139 chip type 'RTL-8100B/8139D'

BUT I have this from ifconfig:

mktg6nt: ifconfig -a
eth1      Link encap:Ethernet  HWaddr 00:02:6F:04:64:6A
          inet addr:192.9.200.42  Bcast:192.9.200.255  Mask:255.255.255.0

          Interrupt:11 Base address:0x8000 Memory:e0500000-e0500fff

and in my modprobe.conf:
alias eth0 8139too
alias eth1 orinoco_pci

I am writting this with my laptop, so it came back up clean.  I just do
not understand the differences in the eth0/eth1 being reversed in the
dmesg output from the ifconfig output.

Should I change the modprobe.conf to have the orinoco_pci aliased to eth0
and the builtin 8139too aliased to eth0?

What is the 8259A interupt?  It seems like the builtin sound card.

Thanks.
