did you add a pci card or reset or change your bios in mobo at
the time this occurred.<br>
looking at other entries for other HW in lspci -vv may show
other differences.<br>
There is PCI irq mapping at play and the fedora vs. ubuntu
kernel are working it differently (i am guessing).<br>
<br>
of course if you change pci settings in your bios (i.e. no
plug and play,and other pci/irq related settings) you risk
nuking your windows<br>
(i know, as its happened to me once years ago).<br>
<br>
you should also look at dmesg of boot time (time frame). <br>
Maybe just update your ubuntu kernel? or pass in some boot
string to manipulate APCH settings.<br>
But why it started to happen in the first place? i am guessing
because of a add/remove pci card or bios change/update?<br>
<br>
-tl<br>
<br>
I haven't added a pci card nor changed bios settings. <br>
<br>
Tracing back my steps, its hard to pinpoint the last thing I
did before it stopped working, reason being that I had the
system (ubuntu) in sleep mode and the changes I made may not
have affected it until I rebooted. I have in fact been making
some network changes and the problem appeared a few days after
making my changes when the system was rebooted. In fact I
rebooted only because the system shut down one day when I
tried waking it up. At that boot and every reboot afterward,
there was no connection. <br>
<br>
What I did was to change the router from my coyote pc to a
commercial box so that I could do dhcp. I bought a blu-ray
disk player that I could not connect to the internet on static
ip, so changed systems. Meanwhile, I kept this one box as
static ip. The dhcp was only for the BD player. And I made
sure that the dhcp numbering was kept quite apart from the
static ip numbers I use. <br>
<br>
I got everything working OK, including the ubuntu system I was
running. Then, after the system shut down instead of awakening
and I could not connect, I started fiddling with dhcp ip's,
ended up with ip conflicts and made a mess of it. But I'm
fairly certain this mess happened *after* I lost connection in
the first place. And I did get fedora and vista connected, so
I was able to fix what I messed up. Except I can't fix ubuntu.<br>
<br>
I had also installed mediatomb, which I have since removed.<br>
<br>
That's the history of it in a nutshell.<br>
<br>
I can't update the ubuntu kernel very easily because I have no
internet when I'm on ubuntu. I'm not a computer whiz, so
upgrading the kernel without using the package system is not
something I have the skills to do. If there are no clues on
what to do to fix it, I may have to re-install ubuntu. Or
maybe try something else.<br>
<br>
Thanks,<br>
<br>
John.<br>

Here's what came out - all I get out of it is that the

I find it odd that eth0 in fedora ended up with irq 25
rather than 22 (from the 2nd line of fedora dmesg), yet
in ubuntu eth0 got irq 23 (from the 2nd line of ubuntu
dmesg) rather than 25.<br>
<br>
Is there a clue somewhere in the above?<br>
<br>
Thanks,<br>
<br>
