Mar 7 23:03:07 z60m kernel: ipw2200: I ipw_handle_missed_beacon Missed beacon: 9 - initiate roaming
Ok, here the driver recognizes 9 missed beacons and tries to initiate roaming, which triggers a scan.
Mar 7 23:03:12 z60m kernel: ipw2200: U ipw_scan_check Scan completion watchdog resetting adapter after (5000ms).
The scan did not finish after 5 seconds. Hence, the driver thinks the card is stuck and triggers a restart. I'm not sure why the scan did not finish within 5 seconds. I counted 18 scan notifications (=#scanned channel) on 11a channels which should not be more than 18 * 120 <= 3 sec. However, the ipw2200 firmware does some scan magic and switches back to the operating channel once in a while. That could explain the timeout.
Mar 7 23:03:12 z60m kernel: ipw2200: Firmware error detected. Restarting.
I guess this one can safely be ignored as it happens during adapter shutdown. Jiri, my suggestion is to simply increase the IPW_SCAN_CHECK_WATCHDOG to something around 10 seconds. I already made such a patch a while ago (see [1]) but it turned out to be a different issue (see [2]) and thus I dropped that patch again.
