Recent kernels are having troubles with wireless for me. Two seemingly
related problems:
a) NetworkManager seems oblivious to the existence of my IPW2200
b) Manual iwconfig waits for 60s and then reports:
Error for wireless request "Set Encode" (8B2A) :
SET failed on device eth1 ; Operation not supported.
During this time, my keyboard in X is unresponsive, but everything
else seems to be functioning properly. Queued keypresses eventually
show up. Alt-sysrq-w gives:
ieee80211_crypt: registered algorithm 'WEP'
SysRq : Show Blocked State

ieee80211_crypt_wep: could not allocate crypto API arc4
eth1: could not initialize WEP: load module ieee80211_crypt_wep
ADDRCONF(NETDEV_UP): eth1: link is not ready
A second attempt to enable WEP via iwconfig succeeds and network
connectivity is normal. However, NetworkManager still ignores the
device at this point.
