More details. If I boot without an active network, wpa_supplicant stays dormant and the system is stable for at least 8 hours. If I boot with one active network, eth0 is my internal 10/100 card, eth1 is my wireless card that I don't want active, eth2 is a pcmcia 10/100/1000 card. If eth0 or eth2 are active, wpa_supplicant consumes ~7-8% of the cpu until events/0 erupts to 80% of the cpu. This makes no sense to me since I don't need (at least I thought) wpa_supplicant for either wired connections. How do I disable eth1 in Ubuntu 10.04? I google it, but google's responses seem to be dated for 9.x or earlier. Here are some log entries from various log files.

I installed 10.04. I have two network interfaces, eth0 is my laptop's 10/100 port. eth1 is my laptop's 802.11b wireless port. This makes replacing the network cards more difficult, especially since the laptop is older and not worth finding a replacement network card. I decided to take my laptop to my day job to debug while my day job's work was simulating. I did not plug my laptop into the network, which is why I unplugged eth0 (not to try and fix eth1).

Thanks again,
Eric

I would hate to see you back out two years worth of advances in ubuntu. I don't think that you ever said which version you just installed, but assuming it was 10.04 or even a 10.10 alpha release, I might be tempted to try 9.10 which was a very good release. On another note, 10.04.1 was released which is the pre-planned patch release for the 10.04 LTS (Long Term Support) and it fixes some things so you could even try that although if you have 10.04 installed you only need to get the updates to be on 10.04.1.

Hmmm, just noticed that you said unplugging eth0 (ZERO, not ONE) fixes the problem. Does that mean you have two network cards? Perhaps you are seeing a conflict of some sort. Why did you choose to unplug eth0 instead of eth1 which you were getting the messages for?

When I unplugged the network cable, eth0, dmesg stays clean.
I'll investigate more later today. As a historical note, I ran Ubuntu 8.10 (I think) for months on this machine. Perhaps I should roll my install back.

A mouse trap, placed on top of your alarm clock, will prevent you from
rolling over and going back to sleep after you hit the snooze button.
