"ifconfig: SIOCIFCREATE2: Input/Output error" never ends at boot.

Hi.

I was configuring my one and only internet source, a USB wlan device, I reboot, and a loop with the text:

Code: 
ifconfig: SIOCIFCREATE2: Input/Output error
ifconfig: interface name does not exist

It won't stop. And heck I can't even boot up now. Any suggestions? I'm guessing it thinks that zyd0 doesn't exist, but I checked and it does, so I'm not sure what's the issue. However, this is the root of the cause, so I need some way to remove a few lines from rc.conf.

Any help appreciated for my first home-built server.

Usually it would be partition f, but if /etc/fstab is accessible, you should just be able to mount -a -t ufs to mount everything.
 
I'm still confused though. My USB zyd device registers as zyd0. However, if I try to configure it in rc.conf, it will not recognize it, and the same result repeats. I'll see if I can find something in the manual.
 
Ah yes. I don't have an ethernet connection to connect to. So, I'm trying to connect to my network through a wireless wpa connection following this guide. My wireless USB device is a zyd stick. It had worked in the past, and I assume it still does.

Thanks.
 
There are probably easier ways than:
rc.conf.bak
rc.conf
OMIT networking from the new latter one.
use wpa_cli and wpa_supplicant to connect.
put the equivalents of (the line above) in rc.conf
test with
Code: 
sh /etc/rc.d/netif restart
to see if it connects without the error.

...
OR some variant. (some file needs an
additional line, say, wpa_supplicant.conf ?
I've read many many parameters that could be
put in it.)

There are errors in that guide, or maybe it's not set up for FreeBSD 8. The short form for most wireless cards is you load the driver, set your SSID and PSK, run wpa_supplicant and DHCP:

/boot/loader.conf
Code: 
if_zyd_load="YES"

/etc/wpa_supplicant.conf
Code: 
network={
        ssid="myssid"
        psk="myultracoolpsk"
}

/etc/rc.conf
Code: 
wlans_zyd0="wlan0"
ifconfig_wlan0="WPA SYNCDHCP"
 
Okay. Thanks for that. It's working like a charm now. However, it keeps spitting out:
Code: 
zyd0: unsupported rate 0

Not entirely sure why. Thanks for the help!

The root console will get lots of messages, many just warnings or notices. You can use any of the other consoles (alt-f2, -f3, -f4, ...) which won't show those messages.
 
Is there a way to control how verbose the root console is? For example, 0 being display all messages, and 5 being block all warnings and errors.
 
Alt-F2 switches to ttyv1, a console with zero system messages, without sticking black tape over the red warning light of ttyv0.
