Bug Description

Hello,
I'm not sure it's the right package where I should report this... but it seems the most appropriate to me.

My issue is very simple. I've got a Dell Latitude D810 notebook, with an ipw2200 wireless card and a broadcom tg3 ethernet card. I suffered from card-name switching (network interfaces got their names, eth0 and eth1, casually assigned at every boot), hence I put some lines in /etc/iftab assigning eth0 to the broadcom and wlan0 to the ipw2200.

Works flawlessly on boot.

But, whenever I suspend or hibernate my notebook and then I resume, my wireless card gets bound to eth1 instead of wlan0.

I thought it was an udev bug, but it doesn't seem the case (i'm attaching the logs), should you need more info or debug output just tell me.

Also: simply doing:

sudo echo mem > /sys/power/state

creates a lot of other problems in the system, but the wireless card doesn't change its name ^_^

It happens on Edgy.

I'm not sure what causes it, by the way in the meantime I did find a sort of 'workaround' by using the MAC selector for the ethernet card, and the driver selector for the wireless card; e.g. this is how /etc/iftab looks now:

# This file assigns persistent names to network interfaces.
# See iftab(5) for syntax.

eth0 mac 00:14:22:f3:87:d9 arp 1
wlan0 driver ipw2200

I noticed that if I tried using the driver for the ethernet card as well (tg3 driver) it was problematic. This seems the only working combo, even though I don't know why.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.
