Comment 23 for bug 50099

I can confirm this bug for Feisty using ipw2100 in a wpa_roam setup. No network management software involved, just a hand-edited /etc/network/interfaces like so:

auto lo
iface lo inet loopback

allow-hotplug eth0
iface eth0 inet dhcp

auto eth1
iface eth1 inet manual
        wpa-driver wext
        wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

iface default inet dhcp

ifup "thinks" eth1 is up after booting (the kernel interface actually is up), but wpa_supplicant and wpa_cli aren't running. I have to ifdown and ifup eth1 after each boot to connect.
