/**** ATTENTION ****
I believe this issue is specific to the error that a chipset that is not 802.11G capable will return when it picks up an a beacon from a router that is not mixed-mode, but 802.11G specific. Please verify. Remove mixed-mode from your G routers, and see if you can get this repeated. Then add back mix mode and see if it goes away and if you're connected with 802.11B.

[ Current Status ]

The ipw2100 driver was last updated on 2007-01-31.  That tarball release
contained an issues file that described this particular bug:

Firmware restart is detected randomly
----------------------------------

After running one or two days, Intel PRO/Wireless 2100 Network Connection
driver will only occasionally restart the firmware.
"ipw2100: Fatal interrupt. Scheduling firmware restart"

To resolve this problem, the system must be rebooted.

Defect #329

[ Original Description ]
Since I've upgrade to Breezy, ipw2100 driver no longer works and in dmesg I've
got plenty 
"Fatal interrupt. Scheduling firmware restart."

I'm always able to do an iwlist :

% sudo iwlist eth1 scanning
eth1      Scan completed :
...
          Cell 02 - Address: 00:07:CB:51:65:E0
                    ESSID:"gaspard"
                    Protocol:IEEE 802.11b
                    Mode:Master
                    Channel:11
                    Encryption key:on
                    Bit Rate:11 Mb/s
                    Extra: Rates (Mb/s): 1 2 5.5 11
                    Quality=92/100  Signal level=-36 dBm
                    Extra: Last beacon: 31ms ago

But the card no longer register. It stays "unassociated" whatever I've
tried :

% sudo iwconfig eth1 essid gaspard key open XXXXXXXXXX mode auto
% sudo iwconfig eth1
eth1      unassociated  ESSID:"gaspard"  Nickname:"ipw2100"
          Mode:Managed  Channel=0  Access Point: 00:00:00:00:00:00
          Bit Rate=0 kb/s   Tx-Power:off
          Retry min limit:7   RTS thr:off   Fragment thr:off
          Encryption key:4D7E-7ED3-1D   Security mode:open
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

Sometimes, it works for a short time and after half an hour or an hour, it crash
again.

I've tried to upgrade ipw2100 and the firmware. No way.
