[Bug 24776] Re: ipw2100 - "Fatal interrupt. Scheduling firmware restart."

[Brian Murray]

** Description changed:

+ [ 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.
