Description of the problem:
I have Belkin wlan card F5D6001, which is supported by Realtek's rtl8180 driver
(according all searches I performed).
The driver loads ok, and initializes the card (according syslog and
messages).
Here I have no wireless access point, so no network using the wireless
card, only wired, if I need to.
It doesn't matter if I have wired connection or not, or if it was
connected before that or not - if I go to Administration/System/Network,
and un-check the checkbox in front of the wireless card to disable it,
the system hard freezes. No ssh to it (if wired connection is present),
no keyboard or mouse activity, no Ctrl-Alt-Backspace or Ctrl-Alt-F1-6 to
switch to text mode. The only solution is power-cycle.
Here are the relevant part of /var/log/messages when the freeze happens:
/var/log/messages:
Oct 1 18:34:18 mubuntu kernel: [ 668.897833] rtl8180: Setting SW wep key
Oct 1 18:34:18 mubuntu kernel: [ 668.946479] rtl8180: Bringing up iface
Oct 1 18:34:18 mubuntu kernel: [ 669.155018] rtl8180: Card successfully reset
Oct 1 18:34:18 mubuntu kernel: [ 669.492580] ADDRCONF(NETDEV_UP): wlan0: link
is not ready
In /var/log/syslog there is nothing interesting, the last message was 4
minutes before I invoke the freeze.
What else can I provide in order to help diagnose the problem?
Cheers
Sunny
