Comment (by [EMAIL PROTECTED]):
I think I have a similar problem. I'm running a fresh install of Ubuntu
8.04 Hardy Heron on an AMD64 box. I have un-installed network-manager to
no avail. Here is the output of: uname -a
{{{
Linux mr-turk 2.6.24-16-generic #1 SMP Thu Apr 10 12:47:45 UTC 2008 x86_64
GNU/Linux
}}}
the output of: lspci | grep Atheros
{{{
04:08.0 Ethernet controller: Atheros Communications Inc. AR5212/AR5213
Multiprotocol MAC/baseband processor (rev 01)
}}}
and the output of: modinfo ath_pci
{{{
filename: /lib/modules/2.6.24-16-generic/madwifi/ath_pci.ko
license: Dual BSD/GPL
version: 0.9.4
}}}
I can run any of the following commands without a crash (not at the same
time, or in this semi-meaningless sequence):
{{{
wlanconfig ath0 destroy
wlanconfig ath0 create wlandev wifi0
wlanconfig ath0 create wlandev wifi0 wlanmode sta
}}}
However, after destroying ath0, if I run either of these commands:
{{{
wlanconfig ath0 create wlandev wifi0 wlanmode master
wlanconfig ath0 create wlandev wifi0 wlanmode ap
}}}
then the system freezes about 2-4 seconds after hitting Enter. It becomes
totally unresponsive to the keyboard (can't restart X with Ctrl-Alt-
Backspace, or reboot with Ctrl-Alt-Del, or get to a text console via the
F-keys, or reboot using any of the Alt-PrintScreen keys). The only
solution is a hard reset.
Upon rebooting, the following can be found in the /var/log/syslog:
