Hello,

while trying to get my wireless to work (a Ralink RT2560, as
sold in a Fujitsu-Siemens Amilo A 1630), I've been hitting the
following Panic twice:

BUG: unable to handle kernel NULL pointer derference at virtual address 00000218
[...]
EIP is at ieee80211_ibss_add_sta+0xae/0x130
[...]
EIP: [<c05773fe>] ieee_80211_ibss_add_sta+0xae/0x130 SS:ESP 0068:f641dc38
Kernel panic - not syncing: Fatal exception in interrupt

The bug seems to be triggered as soon as the stack tries to
join my router's ad-hoc; it happen either directly when
doing "ip l s wlan0 up" as well as when doing
"iwconfig wlan0 essid equinox" (when it did not immediately
find the network).

Kernel version is 2.6.21-ge42d23f4 (git checkout from
git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-dev,
about a few hours old.)

Full information set available at http://celeste.diac24.net/rtpanic/
(includes pictures of the panics, in case I have a typo somewhere)
Requests for more information / patches welcome, but expect delayed
response.

More information attached.


Greetings,

David Lamparter
