I don't use any threads but plain, bare-metal programming. Here lwIP is running in context of the Ethernet-PHY-interrupt(s) while some data are pushed to lwIP from the main-loop.

That's a problem indeed. Seems like you are violating lwIP's threading requirements (search the list or the wiki, there are numerous post about it).
