Hi Linus,

thank you for your answer. (Un)fortunately I can not reproduce the page

The ARM device is a Cubieboard with Allwinner A20 CPU and 1 GiB RAM.

There is no problem watching the originators on an 32 MiB RAM OpenWrt
router with 3.10.49 mips.

I'm sorry bothering you with this issue. Have a lot of fun developing
B.A.T.M.A.N. advanced.

Best regards,
