[B.A.T.M.A.N.] problems running batman rev350

hi list,
i am new here and just trying to use batman rev350 compiled on
2.6.21.1-rt3 kernel on ibm-thinkpad-R50e. the rt-patch (for low-latency
audio work) comes from:

http://people.redhat.com/mingo/realtime-preempt/

i am using a atmel-wlan adapter and the atmel driver from:

git-clone http://honk.sigxcpu.org/git/at76c503a.git/

the driver runs pretty stable, if i use olsrd to join the network here, i use following script to start the protocol:

#!/bin/sh
iwconfig eth2 mode ad-hoc essid olsr.freifunk.net channel 10 ap 02:CA:FF:EE
ifconfig eth2 104.130.30.9
ifconfig eth2 up
olsrd

.........

except of some timeouts, which are pretty rarely, that runs good.

i am starting batman with:

#!/bin/bash
iwconfig eth2 mode ad-hoc essid olsr.freifunk.net channel 10
ifconfig eth2 105.130.30.9
ifconfig eth2 up
sleep 1
batmand -d 1 -p 105.131.41.5 -r 1 eth2

and

#!/bin/bash
batmand -c -d 2

in another terminal.

when batman starts, the 'batmand -c' script shows, that i am connected
to another gateway, but not to preferred one:

Gateway Router (#/128)
=> 105.192.99.62 105.130.30.1 ( 3), gw_class 10 - 6 MBit,
reliability: 0
105.192.99.61 105.130.30.1 ( 1), gw_class 7 - 2 MBit,
reliability: 0
105.131.83.5 105.130.30.1 ( 1), gw_class 11 - >6 MBit,
reliability: 0
105.131.41.5 105.130.30.1 ( 2), gw_class 11 - >6 MBit,
reliability: 0
105.192.99.103 105.130.30.1 ( 3), gw_class 7 - 2 MBit,
reliability: 0
105.192.99.192 105.130.30.1 ( 2), gw_class 10 - 6 MBit,
reliability: 0

...........

this always is a number 105.192.99.....(.62, .103, .192).
this condition than stays for 2 or 3 up to 10 minutes, and in that time
i cannot even ping the 105.130.30.1 which is the next point here.

after some minutes, the connection changes, so that 'batmand -c' shows
that i am connected to 105.131.41.5 and i am able to ping 141.1.1.1.
unfortunately, after some minutes (or even shorter), the batman script
stops and the terminal is at the prompt again. there is no segfault,
using 'ulimit -c unlimited' will not produce a core-dump. i suppose that
this is not a driver bug, cause looking at this moment at 'dmesg', i can
see that the driver is loaded using the 02:ca:ff:ee:ba:by - if i stop
batmand and start olsrd, i will be connected to the internet as expected.

i am really not aware of what else information i could provide to you,
in order to make batmand running stable here, but if you have any idea,
please let me know!

cheers,
doc
