[ipw2200-ap-devel] ipw2200 keeps restarting

[Thanh H. T. <han...@gm...>]

Dear list,

I have installed ipw2200-ap (latest version
ipw2200-ap-0.3.tgz + corresponding firmware) in order to
turn my laptop (IBM ThinkPad R50e) into a home AP. It works,
however from time to time it keeps restarting the firmware
randomly. Some relevant messages from dmesg look like this:

,--------
| ***** FATAL ERROR **************************************************
| ipw2200: Firmware error detected.  Restarting.

`--------

when this happens, unloading the module (by 'modprobe -r ipw2200')
gives:

,--------
| Badness in remove_proc_entry at fs/proc/generic.c:693
| [<c018ec3a>] remove_proc_entry+0x10a/0x150

`--------

and reloading gives:

,--------

| ieee80211_crypt: registered algorithm 'NULL'

Does anyone have a clue how it could be fixed? I am using
debian sarge, with a customized kernel 2.6.11.5.

Thanks for your consideration,
