wifi stops unexpectedly on linksys wrt54gl

Description

hi,

we have problems using adhoc wifi mode on brcm47xx devices such as wrt54gl.

the routers use olsr for weimar.freifunk.net as routing protocol and wifi stops working for example by starting a huge download (linux iso images) after downloading a few megabytes.

we use the current openwrt trunk with b43 drivers.

now we enabled Kernel debugging, Kobjectl debugging, debugging info and runtime debugging and we're happy to see some debug output:
