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. Here are some log entries from daemon.log.
